I’m a fellow straight person who has had a gay person hit on me. Here’s the thing: the problem wasn’t his gayness. The problem was his persistence. If he had hit on me respectfully, and backed off when I showed disinterest, everything would have been fine.

His persistence wasn’t due to his gayness. There are gay people who are not persistent.

A lot of straight people are persistent too, and it’s just as much of a problem in straight people as it is in gay people, it just doesn’t bother you specifically, because you’re straight.
