You think there wasn't in times gone by. The Roman Empire had a list of ones they didn't like called "mystery" religions, and they included all the ones that refused to worship the Emperor, because it took away revenue from the state temples.

Yes. Nowadays one religion tries to establish domination over the other. In India it's common. People don't understand religions are just a way to reach God.

It's not a new thing. Religions have been warring for thousands of years.

There's ALWAYS been competition among religions. There's always been competition WITHIN religions. Pretty absurd, isn't it?

Yes

I think that with the exception of some fundamentalist Christians and perhaps fundamentalism Jews (although I live in NY and haven't met any yet) Jews and Christians seem to get along, especially protestants whose Calvinist work ethic seems to mesh with Jews' Jewish work ethic. [Joke] Only at the very uppermost echelons of society do they really compete: national politics, high finance, setting of legal doctrine. That said, Jews and WASPs do (relatively politely) compete for control over control of the Western world and WASPs pull out "morality" and Jews pull out their "innate" intelligence as backroom arguments. I believe it's more of a cultural or perhaps ethnic thing than a religious thing. Most of these people aren't too religious anyway. I am a secular 1/2 Jew and I work at a Catholic non-profit and I do sometimes worry that they are condemning me to eternal damnation behind my back but I don't let it interfere with my work. Buddists don't seem too competitive, nor do Hindus. Muslims on the other hand- between their Fatwas to kill people for writing books, jailing dissidents of the mildest variety, and their orders to kill all non-Muslims, men, women, and children, Islam does seem to have a bit of a competitive streak to it.
