That's fucking disgusting. "There's no song called 'I kissed a trans man'" LIKE? that's not the point?
Do you think that kissing a trans man is inherently disgusting?
Maybe, maybe not. It's not a big deal what I think.
Well if you do view trans people as disgusting, that can really be hurtful towards other people. Trans people suffer a lot from bullying and not being accepted. You should read about the difficulties they deal with so you might be more open minded toward them.
