Does expressing hatred have a sort cathartic effect on the spirit?

There is a lot of expression of hatred here.

In the past, for anyone who disapproved of Barak Obama, always for Republicans and “corporations”, and currently for Donald Trump PLUS anyone who does not openly despise him whether they voted for him or not.

This must be doing some good. In war, it makes killing a little tiny bit easier. But there is no catharsis in war. It still feels bad after.

I assume though, in this case, it must have some positive purpose or people would avoid it so they don’t feel bad later.

Is the end result of this a “cleaner” and happier spirit? If so, let’s all join in!
