someone I'd wanna be in cockpit with.

Here again, you're making an ad hominem argument. You're talking about the
person, not the topic at hand.

Additionally, "Buttman" could mean all sorts of things, and isn't necessarily
an indication of homosexuality.

And furthermore, not everyone considers adumbration of homosexuality
pejorative, so your thinly veiled insult might well be without effect.
