They're genuinely scared they will end up on some list, and Trump or others will take their revenge. Because it's been done so much on the left, the return volley is now scary to them.
Since they truly believe Trump is Hitler, they're expecting camps. So, they are deliberately keeping their mouths shut until "freedom reigns".
The others are trying to conspiracy theory the idea it was fake, or act like it never happened.
I hope the leftists are afraid. Maybe they can scurry into the rathole in which they belong and die there, alone and forgotten in their final days, without anyone's love, and leave the rest of civilization in peace, free of their cancer.
