What do you think of me calling slutty cosplay strange and weird.
Why do you think it's weird?
I just don't like it. I don't want to look at them.
It's fine that you don't like that kind of cosplay, as long as you don't act rudely toward those cosplayers, or make negative remarks. Not everyone has to like people who dress in a certain way.
Well I prefer that people wear normal clothes. People who wear slutty costumes are just attention whores.
I would suggest to avoid conventions if you really don't wan to see these kinds of costumes. Thinks like anime might also trigger your feelings. But remember everyone has the right to dress how they like.
