I've been progressive my entire life, but I've broken with that herd specifically because of the horrific group think, shaming, intolerance for diversity of thought, toxic degrees of ruthlessness and inhumanity, etc. It's like we've time warped back into the 1600s and instead of the church shaming people into alignment with accepted practice and thought, it's the social justice advocates shaming people into alignment with accepted practice and thought. And, just like the church felt back then, social justice advocates are utterly convinced they have the moral high ground to do so.

I've torched my Facebook, Instagram, Twitter and other social media accounts specifically to protect my career from blowback like you describe, but also because most social media have become enforcers and participants in this trend, not neutral traffic cops. 

It's simply not worth the risk to engage except face to face where their courage evaporates.
