That's a nice take! It is indeed the absurdity of it all that probably does it. My comment was more of a shower thought inspired by this post than a direct reaction to it.

As you can probably tell from my choice of pronouns, I'm still figuring out what the concept of "being gay" even means to me. Though there's probably no point to doing so. Which only makes being called gay even funnier to me.

That, and of course the ridiculous concepts of what does and does not make you gay, that are going around. But that's part of the original joke.
