I think it is okay to say you don't care for a show or an actor and no one will get their feelings hurt. I do think it is plain rude to go to a show site simply to bash a show or the actors (and I have seen that happen.) I actually like
Bewitched. I think it is a cute show, not my favorite, but okay. I doubt anyone here would be hurt that you don't care for it. But if you went to the
Bewitched board and starting making threads about how much you hate it or replied to others posts with rude or hateful comments, they would probably get hurt. (Of course I know you wouldn't do that!)
The only time I feel uneasy about posting, or worry that I will hurt someone's feelings are when people post things in ChitChat asking for advice or debating topics. I get scared of upsetting someone or having others lash out at me for my opinions. That's why I stay away from here most of the time. Don't know what made me actually reply to this...I guess I am getting brave!
