Just because it's Geocities doesn't automatically make it wrong or unacceptable in a debate.
If you don't care anyway, think of it this way: the Y chromosome is NOT present in the mother until the sperm delivers it. Y chromosomes are treated as invaders and antibodies are built up. Over time (IE: lots of sons), the antibodies attack the Y chromosomes, and the mother's system naturally repairs things. Since the mother doesn't have any construction info about the Y chromosomes, it improvises. As for first-born male gay sons, or any LGBTQ for that matter, nobody is 100% certain of what's going on.
Homosexuality was considered a mental disease until a few years ago. It was removed because unlike EVERY OTHER mental disease, it cannot be treatable. Why? Because it isn't a mental disease.
Until you stop bashing them, especially when you don't KNOW any, I refuse to discuss this with you anymore.
@CrAz3D: Ridding society of a specific group of people because of bias is called "genocide". You may remember this happening to the Jews or the Tibetans. It's also banned by the Geneva convention, which is extremely important. People in other societies believe what they believe, and you know what? You're not in their society because you don't agree.
Singling out any group of people because you do not consider them "good" or you think they are "inferior" is called prejudice. Acting upon this by exterminating ("cleansing") the world of these people is GENOCIDE. If you all agree with genocide, how about you go join the neo-nazis?
