That is ridiculous. If a kid has a mental disorder that stops him/her from developing as a regular human child, and has not learned to talk yet, and you and I both know there is something wrong with him, then that is clearly different from a man expressing his feminine side through wearing dresses. Children do not just magically chose rather or not they want to have a mental disability that incapacitates their ability to verbally communicate with other living organisms. A fully grown man can choose what they wear, rather it be a tight dress or trousers. Both of those are not normal. Nothing is. So it is pointless using the word.
You literally typed, "he deserves every comment he gets". So it was reasonable for me to believed that you claimed he should be beaten and/or assaulted, because he did receive those comments.
If a man actually considers wearing feminine clothes - because he believes it's 'expressing himself' - then yeah, there's something wrong with him. His head is not functioning properly. This isn't different from other mental disabilities.
