I really don’t think the Left “denigrating” Trump supporters is the big problem here.
They’ve been doing that for years.
They are now using words like “reprogramming”. You don’t even need to know much history to understand THAT.
This used to be called “BLACKLISTING”..
It took a little longer than I anticipated (only because of normalcy bias, lack of American memory and ability of humans to get comfortable with less, well, comfort)
But, here we are.
