Did you have some particular 'point'? My brother made the varsity team in wrestling when he was in high school. He was pretty much a "progressive liberal" all his life.
The pro wrestler maybe shouldn't use that forum to insult audiences, but according to your link, most of them do that. It seems this particular wrestler (heel) is so "hated", simply because his insulting banter is more politically specific?
In wrestling they do this to get heat.
