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.
Either one works I'm sure lol it will vary from leftist to leftist, but when you realise what sort of families and backgrounds a lot of them come from it does make a lot of sense they live in a bubble and can't fathom anybody other than a racist hillbilly would disagree with them.
