Supposedly, a child with gay parents does not have a greater chance of becoming gay than a child with straight parents. I buy that. I would guess that two scenarios would come into play in this situation. Either the child witnesses the habits and behaviors of his/her gay parents and sees it as normal (greater chance of being gay) or willingly accepts them even though they know these behaviors are weird. (less chance of being gay) If a child is surrounded by homosexuality, my bet is that it is almost impossible that they will turn out the same way.
