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.
That's basically the only way I've been able to have a conversation with them.
Conversations are more productive with them when it's not political, but it's weird that we are ignoring the elephant in the room.
