Either way, does it matter if they are supporting the effort? "Just following orders" was not a defense at Nuremberg.
I think it matters because we have two separate problems with separate solutions:
1) Some Leftists are stupid and believe the lies about MAGA and Trump.
2) Some Leftists are evil - they are the ones spreading the lies.
The solution to #1 is to try to educate them and win them over.
The solution to #2 is to try to expose them and destroy them.
Unfortunately, I can’t always tell which is which.
