PBS and all Leftists think civility only exists when everyone agrees with them.
When people do not agree with them and their agenda why then... protests and riots and violence are 'necessary resistance' to 'right wing fascism'.
So now that the divide has been made manifest and irreparable, to blame the incivility on Trump alone showcases what one expects Leftists to do in terms of blaming their targets and dehumanizing them for creating a sense of moral duty to impose punishment or to do violence upon them.
That said, Trump has only widened this divide and encouraged reciprocal action and delight in 'payback'. We now have divides that are irreconcilable and all that remains is how long it will take before enough of the mob recognizes we can no longer peaceably coexist with the other.
Where a society goes when it reaches the place we have now arrived, is historically, a horror and a terror.
I know, I know...
..that cannot happen here.
The truth is, yes it can and yes it is.
