People who think being gay is a choice are either gay and in complete denial or bi, because as a straight man, while I could choose to have sex with another man, it has negative appeal to me. Like not just no attraction, but repulsion.

So either they are in denial about their own sexuality (especially the ones that make comments about vaginas being gross), or they are so stupid they listen to their thought leaders over their own experience of it not being a choice but biologically imprinted deep in their psyche.
