Whats your argument for gay/lesbian isnt a choice its “who they are”?
Are people born prostitutes, crack heads, race car drivers, child molesters, murderers, pro athletes, genius’s, etc.? NO. They were more or less molded into what they “are” because at the time they took an interest (so be it habit, necessity or just plan curiosity) to do so.
Society makes the person… simple as that. Nature adapts to its surroundings. Simple example. If some girl gets cheated on, dumped, raped, etc by some guys, and at some point she thinks, fuck all that shit I am done with guys I am going to chow beaver from now on, and becomes a lesbian… she did so by choice and circumstance… not by DNA.
