The problem is: If anybody upload a video about X celebrity, sure 90% of the viewers will be fans of that celebrity. This is specially true in music, films, tv shows and similar categories. Unfortunately, people can't respect oppinions. These people thinks only they have the reason and the truth.The best you can do is avoid posting in those videos. You already know you'll be bad rated, people will hate you, you'll suck, and so.What I would do in this case, is just open youtube, watch all videos, and avoid comment in those "religious fans" videos. There are lots of videos where you can post, formulate ideas and exchange opinions (like educational videos, documentals, independient productions and so).
