Destroying someone’s life for having the wrong opinions is not charitable to their humanity. It is not how America was until very recently. Sure, people have always been vilified for their views, but they’ve most times been able to continue making their private living nonetheless. Deviations from that, like the McCarthy Era, are rightly seen as wrongful failures to live up to this ideal.
As for the “rich and powerful”, do you mean high school kids making inappropriate jokes that become national news stories, blue collar guys being fired for not being up-to-speed on 2020 cosmopolitan sensibilities, or anyone who says a single negative thing about BLM riots?
