Why do so many people hate cosplay?

The most direct reason is that the three views are different. Some people don't like animation at all, let alone understand something like cosplay that takes energy and money. Also, just like the difference between open and conservative standards, some people just think it's a hobby, while others think it's a little grandstanding. I like anime, but even I feel the same way about my favorite cos character at most. For those who don't like it at all, I can only look at it from the most intuitive cosplay appearance. To tell the truth, some characters' clothes are exposed, and I don't like this type of COSPLAY either.
