Maybe you might want to consult a dictionary then. I don't have to as I know what it means and I know meaning of it includes neither "humorous", nor "looking for the worst".
In addition to that I'm also following plenty of other critics with various views on each subject and I would never have the arrogance to completely dismiss someone's critique just because some preconception even if it wasn't completely misguided and (clearly) frankly I find it doing such a thing pretty insulting.
