So someone else's strong feeling makes you uncomortable, and therefore they should be silenced and outcasted, yes?  Or they should reword it so that you're not uncomfortable?

Do you think that every post with dissent needs to cater to your personal sensibilites? 

 

Now abuse, stalking, insulting or assumed superiority should be dealt with, but dissent, no matter how catty, is just dissent.  Some people feel that their cattiness is in itself art to some extent.  For example, Cathy Griffin.
