Then don't follow them. Easy peasy. YOU chose to follow their twitter, if you don't like what you read, don't read it.
I'm not a star hound, I could care less about the tweets of people I don't know personally. I have FRIENDS that have different politcal views than I have, they are still my friends AND we can tease each other about it.
If you choose to no longer see their shows (or whatever) then don't -- but then you shouldn't whine about it. I have eliminated a few people -- but not because I tred on their thoughts (twitter) but because of their actions: mainly Mel Gibson.
If we're not having fun, then why are we doing it?
These are DISCUSSION boards, not mutual admiration boards. Discussion only occurs when we are willing to hear what others are thinking, regardless of whether it is alignment to our own thoughts.
