As a teen in the 80s, I was a conservative on a debate team full of liberals, including members of the Young Communists. Guess what- we were all good friends despite being ideologically at odds.
Having room to rationally discuss our differences makes for an ability for a pluralistic society to have open debate without rancor and violence. Using well formed argument rather than vitriol and public shaming to truly convince rather than force public agreement and private grievance seems to me a better recipe for a harmonious and just society.
In fact, this conversation has inspired me. I interview for SWE positions. It's time to stand up against these people. I will argue against hiring anyone whom I suspect would engage in shunning/shaming someone for failing to fall into line with progressive dogma; I'll find excuses for making the argument on technical grounds.
