> Keep in mind that moderates who dislike Trump from the start can fairly blame left-wing shenanigans, at least partly, for the rise of Trump.
Yes, but it would be a fig-leaf. A large number of them are pretty much on the record as being pissed off that a black guy became president. America really has a race problem even if on paper it is all pretty good. Especially the heartland. Denying this is allowing it room to grow.

Well, if you purposefully skew the weighting of the responses of the various parties to the point where you feel the violence on the 'left' is the equal of the violence on the 'right' then you're part of the problem. It becomes an 'us versus them' thing and staking out a position in such a polarized environment is something that you should do with great care. I'm not aware of any left leaning politician that has tacitly or openly condoned any violence on the left and some (definitely not all, for instance the Scalise shooting) was a direct response to other violence.
To toss that all onto the same heap is disingenuous at best.
If you want 'healthy dialogue' you're going to have to come to terms with inherent biases first. But that's hard to do.
