some straight guy i was friends with was obsessed with me. he only cared if i liked men and had a bf for some reason, and would ignore that i liked women. he would act like i was straight and that if i dated women, that just meant i was single and obviously interested in him.
I think the simplest answer is that we humans can hold two contradictory opinions at the same time. There are people who can support free speech and then censor books willy nilly. There are people who believe strongly in a religion but brazenly violate its rules of conduct on the regular. There are people who know homophobia is wrong but still are homophobic. And if this man has the hots for you at the same time this may be his way of squaring that circle.
I don’t know you. I don’t know him. Insert heaps of salt here. This doesn’t sound like a good friendship to pursue.
