Stalin's in the Closet

Michelle: Where's Stalin?
Mrs. AP Euro: Stalin's in the closet.
Here's the real question: is it homophobic to laugh at that? I don't think so.
I vaguely remember some article or pictures somewhere of a bunch of nude drawings that Stalin censored and wrote things on. Whatever he wrote, it made someone think he was gay. I got on google (because that is what I do) and found this and this piece of crap and this. Cooper Union, why do you have to be so hard to get into and so cool and so free?
It seems like sexuality has come up in about 16 bizgillion conversations of late.
I do not know why that is.
