You cannot be sure that it isn't because most people of a different religion such as Buddhism or Islam usually speak a different language.

Most people who say that aren't really religious. serious christians never use the lord's name in vain. The people who do, use it as an insult. Another reason is that countries where Islam and the like are the most popular have very strict rules. You may be killed or torured for using such a profanity. Christianity has the highest membership of all religions, so Jesus is a house hold name. In America, you would offend more people using Jesus than Dali Lama.

I am sure there are several reasons. One is tolerance. If you go to a muslim area and start associating the name of their prophet with profanity, you may not live long. Christians, while saddened and offended by the vulgar abuse of the name, do not generally take it upon themselves to punish blasphemers. One is the nature of profanity. Those who do not take Buddah seriously will find no satisfaction in abusing his name. Profanity by (at least one) definition must attack something held as holy. If Jesus was not recognized as "holy" in some sense his name would not have come to be abused in this way. I think the abuse of Jesus name may have started with genuine prayers: unlike followers of other religious leaders, when Chrisitans were in immediate distress or danger they might literally call out loud to Jesus in prayer for help or deliverance. Others who did not love and respect Jesus picked up on calling out that name when distressed, and started bellowing some form of the name when hurt, angry or frustrated, and then insert other vulgar or profane word use along with his name. I admit this is speculation, but it seems reasonable to me.

One way i have heard it is that Satan specifially attacks True Christianity because it is the only "religion" that poses a threat to him. BTW some people i know personally will use "mohammed" as a profanity.

Much of it has to do with blasphemy laws and the fact that some cultures are more respectful than others are. This is true of some European countries that embrace Christianity. Buddhists, Muslims and others appear to have more respect for a higher being/God than Christians do. (a generalisation only) In the US freedom of speech protected by the First Amendment, allows for the use of expletives in a profane manner. Often expletives are heard between Mo and Hammad but usually spoken by Christians not Muslims. Again obscene expression and profanity toward God is protected by the US First Amendment. ---------------------------- Blasphemy has been a crime in many religions and cultures, wherever there is something sacred to protect. Socrates was prosecuted for blasphemy, and Mosaic law prescribed death for cursing the name of God. Jesus was tried for blasphemy, while Christians regarded the action of the Jews in trying him as itself blasphemous. Secular modern states often retain blasphemy laws, but they are infrequently enforced. In the United States, state blasphemy laws remain on the books, but the Supreme Court's expansive interpretation of the First Amendment to the U.S. Constitution makes it likely that any blasphemy prosecution would now be regarded as an impermissible establishment of religion. In countries governed under Islamic law, the concept of blasphemy is broad, embracing many kinds of disrespect or denial of religion; the condemnation (1988) of the author Salman Rushdie by Iranian clerics is a recent example of theocratic action. There has been a recent tendency in Western countries towards the repeal or reform of blasphemy laws, and these laws are only infrequently enforced where they exist. Such laws still exist in several countries, such as in Austria (Articles 188, 189 of the criminal code), Finland (Section 10 of chapter 17 of the penal code), Germany (Article 166 of the criminal code), Italy, Ireland (See: Irish Constitution), The Netherlands (Article 147 of the criminal code), Spain (Article 525 of the criminal code) and United Kingdom. In the United States, the First Amendment guarantees a relatively unlimited right of free speech, although some US states still have blasphemy laws on the books. Chapter 272 of the Massachusetts General Laws states, for example: Section 36 (http://mass.gov/legis/laws/mgl/272-36.htm). Whoever wilfully blasphemes the holy name of God by denying, cursing or contumeliously reproaching God, his creation, government or final judging of the world, or by cursing or contumeliously reproaching Jesus Christ or the Holy Ghost, or by cursing or contumeliously reproaching or exposing to contempt and ridicule, the holy word of God contained in the holy scriptures shall be punished by imprisonment in jail for not more than one year or by a fine of not more than three hundred dollars, and may also be bound to good behavior. http://www.answers.com/topic/blasphemy

Its basically just the culture and development of the English language: I have to admit I use "Jesus Christ" with an expletive all the time and, like most people who do, though I'm not remotely religious I don't wish any specific ill on Christians. The main reason I use it is because growing up I heard my parents and other adults use it, and it became ingrained in my psyche as a swear word like any other, I don't mean to be purposely blasphemous, I don't really think about it that much. So the best answer is probably something along the lines of "because we always have". Other languages haven't developed in the same way, but have different, slightly odd sounding swear words- for example the direct French translation of "to kiss" (baiser) is actually pretty offensive to a French person, around the same level as "to f**k", even though its not really a swearword as such. It just happens that our language developed in such a way that the principle figures of the religion most familiar to us ended up being swearwords. I think (just a theory) this has possibly become more acceptable because the Christian Western world in general has a slightly more lax attitude towards religion- for example, a great deal of people (with notable exceptions of course) will describe themselves as "Christian" or believing in a God who best equates to the Christian version, but never attend church, can't say the Lord's prayer and only really give God a second thought when asked if they believe in him. So breaking a commandment isn't such a big deal. Try going up to a random Muslim and asking for a passage from the Qu'aran or to recite the 5 Pillars of Islam and you'll get a much more knowledgable response.
