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.
Stings even more for them because they are wrong and they know it. All the times they shit on you they knew they were wrong and that they were gaslighting you. Imagine knowing deep down that you are and always have been completely full of shit and that all your ideologies are based on falsehoods and hyperbolic lies.
