AITA for unfriending my heterophobic friend?

Hey y’all!

So I have a friend and we’ve been friends for like 2 years. He’s gay. Remember that.

We’ve had like 3 other friends and he always accuses them of being gay. And I’ll admit maybe one of them is bi, but the rest seem pretty straight to me.

He keeps telling me that they are just probably lying about their sexualities cause they’re scared to be gay. But I think he needs to respect their straightness.

AITA because he refuses to accept that some of our friends are straight?
