There are different theories as to why homosexuality/bisexuality exist. If you can't acknowledge this fact, please don't post and go away. >.>
Nature:
Some argue that it is biologically determined, and there's nothing
that can be done to prevent that individual from becoming homosexual/bisexual. If humans are part of the evolutionary
process, and homosexuals obviously cannot partake in producing offspring and in evolution, why does homosexuality exist?
Could it be a commonly occurring genetic mutation?
Btw, is this position beneficial to the gay rights advocacy campaigns? (I ask because some people say that activists who support this side of the argument are actually hurting their campaign)
Nurture:
Others argue that it is due to various external social/cultural factors,
and that these people could have been heterosexual, or that they can change back to being straight, or that
homosexuality/bisexuality could have been 'prevented'. Then, are homosexuals/bisexuals mistaken in their
sexual identity? Do you think it's possible to 'convert' them to heterosexuality?
Nature & Nurture:
There are other theories that combine the two sides of the nature vs. nurture debate on human sexuality.
So, where do you think homosexuality or bisexuality comes from? Feel free to bash any theory - just don't place value judgments on homosexuals and/or bisexuals.
