I'm not OP but I imagine they might be thinking that Trump will find a way to punish it, with him being a fascist and all. Just imagine you'd had done this with Hitler in 1932. By 1934 your life would basically be over.
I never thought americans were this weak and pathetic. Y'all always screamed about "muh guns" and stuff like that, but now... You're just sitting idly while your new king takes over, even discouraging others to do anything that may upset your supreme ruler?
(To be fair, though I'm not in USA / an American, if we're going to stereotype and generalize unfairly, it seems it's largely the "Muh Guns" folks you refer to that support/vote for Trump and the like).
