Accusations and ridicule only stoke the cultures of hate and negativity.
It seems to me you're stoking that fire as well.
How? Don't I discuss issues? If I describe something that is negative, I explain why. If I criticize socialism, for example, it is to understand and discuss socialism with its proponents; not to ridicule them into exile or extinction.
Democracy is supposed to be a forum for reasonable discussion, not a competition for winners to eliminate losers from the discussion. People like Bernie Sanders and Ocasio-Cortez represent other people who believe in socialism for whatever reason, so we have to engage them in discussion to respect their thinking and goals while explaining why we want to solve problems without socialism because of the reasons socialism is bad.
Shouldn't proponents of socialism listen to those who are against it and respect them instead of just dismissing them and trying to overpower their dissent with political maneuvers?
