I'm gay.
My dad is not pleased with this fact. Completely homophobic.
Half the time his homophobia doesn't even make sense.
>Fishing show on TV in the living room
>Watching it with mom and dad
>Mom: "I don't have the patience for that kind of stuff
>Me: "It doesn't feel like too long when you're out there"
>Dad: "Time flies when you're a faggot."
>Go to my room
It's getting ridiculous. He goes out of his way to respond to everything I do by calling me a fag.
The most vocal homophobes probably aren't mostly a 0 on the Kinsey scale even if they're heterosexual given 0s probably are not the majority. Especially the kind who act like it's something that's okay if you hide it or think you can just turn it off, as described in OP's case.
Calling a 1 "gay" is obviously misleading, but from the perspective of many homophobes those occasional thoughts are problematic.
