I know a vegan. A friend of mine suggested that the vegan I know is gay. I said,
"I don't think so he has a girlfriend."
"Ahhh that doesn't mean anything." Said my friend. "No, I think he's straight. I think what you're picking up on is the soy."
"Yeah, he's a vegan. Therefore he eats a lot of soy and soy is natural estrogen. He's probably a little effete because he's got all this soy estrogen in his body."
