Don't like the "GOTCHA!!!" moment when it's used against you?
I dare say you are not an expert on human behavior or sexual attraction. You do not know if people are born gay, straight, bisexual or asexual. In fact, when confronted with your lack of knowledge on how people are born, you quickly, within minutes, agreed that people could actually be born with no sexual attraction to either sex after denying such a thing could ever happen. You've also agreed that sexual attraction, despite your lack of expertise, could change from one sex to the other.
Nonetheless, back on point, one of your main contentions has been that gay people do not choose to be gay and, therefore, should be given the same rights to marriage. You have contradicted yourself, repeatedly, over the last 3-4 pages.
While biz is batshit crazy(or an expert troll), he does stick to his argument regardless of how retarded it is. Maybe you could do the same.
