Bistiza, you're an idiot, so it doesn't surprise me that you don't know what the word "preference" means, but I'll just check the dictionary for you:
"That which one prefers."
"That which one chooses."
Sexual preference is not a choice. Who you choose to have sex with is a choice. But not sexual preference. I thought we had gotten past the point where people at least smart enough to put pretty-sounding sentences together would go around proclaiming being gay as a choice, but obviously not...
I wish you'd respond to the questions about having sex with men... If it's a choice, you could do that, right? Just flip the switch in your head and change to a homosexual preference. Right?
