I came across a quote some weeks/months ago. I couldn’t recall who said/wrote it nor its exact words, but it was referenced the other day by the Zman and so thanks for that:
Hatred is the most accessible and comprehensive of all the unifying agents. Mass movements can rise and spread without belief in a god, but never without a belief in a devil.
Nothing explains the increasingly odd behavior from the left over the past 20, 30 40, heck, 50 years (to bring it all back to the riots at the Democratic convention in Chicago in 1968), like this quote.
In looking for validation of this quote, I found out about Hoffer’s books, in particular, The True Believer, from 1951.
Update (20210718): I’ve enhanced that quote above by including the sentence that comes before. Second, this final sentence/paragraph references a site that doesn’t exist anymore.
I also found this site, which I need to explore more fully.
