People are born gay, and there is scientific evidence for it -- two ways!
1. "Too many Sons": With every successive sibling, you increase the chances of being homosexual, due to the lack of testosterone you receive while in the womb. The antibodies from within the womb get progressively more advantageous due to being weaker than the older brothers, and the target is "masculinity".
2. The actual gene: Much, much rarer than the first, you can actually receive the gene for homosexuality, regardless of sibling number. This is what some people call "the manly, macho homosexual".
