Antigone....this one is a stretch. Dating outside one's gender is necessary (at least for now) to keep humanity alive. Both sexes are designed to fit with each other like puzzle pieces. The equipment is designed for that purpose. Homosexuality (that's your underlying issue) is not what peole are designed to do. None-the-less humanity is drawn to it by (insert whatever theory you like here). It is part of nature. But, despite being unpolitically corrrect here heterosexuality is the normal use of the gender design we have evolved into. No amount of wishful thinking or legislation (state or federal) will change us. I am not saying homosexuality is wrong. What I am saying is it is outside the design of our species. In this respect, the argument between right, wrong, civil rights, etc...is irrelevant. The debate over race, can be boiled down to this...ignorance. The human race should have evolved beyond petty things like skin color. sadly, it has not. This is not therefore a biological issue, it is a cultural ignorence issue. This needs to change. Unfortunately, I fear it will not. One issue is biological and out of our hands. The other is social bias and is within our power to change. I hope some day we will "evolve " far enough to do it.

Antigon that is a very interesting question. Of course keep the human race going is the reason. However I see your point we question everything else.

there's plenty of silly people out there, they are in the majority but that doesn't make them right :)

We want, and we want others around us, to date "one of us". But what we mean by "one of us" is very culturally determined. However, all communities contain both males and females. Many of us have parents and siblings of the opposite sex; if we don't we have schoolmates and their parents, teachers etc. So people of the opposite sex are always included in "one of us". What makes someone "not us" or "them" can be so slight as to be invisible to the outsider, and in Norther Ireland and former Yugoslavia. Ir it can be highly visible, such as a skin colour not common in our community. So the line is invisible , and culturally drawn. What, I think, can be harmful is single-sex education (such as I suffered). A minority of the boys thus brought up never managed, I think, to see women truly as people, and treated them only as sex objects and brood mares, to the consequent unhappiness of all. I got the opposite problem, of seen all women as superior beings and being unable to imagine that any of them would have any interest in me.

thats actaully quite funny. And to be honest I dont know why is still matters...to some people it does i suppose. I personally would like to have a child with someone of my race so that the kid looks like both of us...but that is just what i want, not right nor wrong.

Yes, you would thnk that dating is really going too far. To populate we only need the ingredients to mix, not the containers.

It's called common sense
