You should view your @Twitter feed as a finely crafted interactive experience. Chip away the accounts that steal your joy or cause you angst - they are unnecessary in your experience of life - grow the list of people who bring value and enrichment and civility.
You do need to experience 'the other side of the coin' and you should be able to hear a different viewpoint, but it does not have to be acerbic or insulting. The smartest people do not resort to making you feel like a fool. Instead, take charge of your account and make it
a place of enrichment and strength, fun and joy. Twitter, after all, is not a necessity of life. So craft it into the best it can be, and help to make it a source that creates the greatest good that it can.
