I don't care about the specific prediction about sending the guard to Chicago. I'm interested in the larger prediction that he's doing this only to fight crime and homelessness. But really, the prediction isn't really the issue.
The difference between you and the other examples is that nobody here is actually supporting a stock market crash. Nor the prediction that there won't be elections. Those are doomsaying. Those are the predictions of a dystopia that we want to avoid. Those are the reasons to oppose Trump, given that he shows ALL the signs of being an authoritarian and no signs of anything else.
You, on the other hand, support Trump. That is, you are actively cheering what he is doing. If he goes full fascist, then you will have contributed to that in a way that none of the doomsaying posters have done. If he goes full fascist -- many would argue that he already has, with some persuasiveness -- you will have ignored the many, many warnings and been a cheerleader and supporter all the way. Why shouldn't you have to answer for that? Why should we give you and your ilk yet another chance to destroy the country?
This would be true on the left as well, but of course, there is no precedent for Trump anywhere on the left, save possibly the extreme fringe (and even then it's debatable). Nobody in history has run roughshod over our system of government like Trump has. No DOJ in history has been as mendacious in court. No administration has been as corrupt, and it's not even close. No administration ever has committed itself to a policy of "always lie" and certainly none have approached Trump's level of bullshit fascistic propaganda.
Why should you get another chance to ruin democracy, given that you tried once and failed and then tried again and in this narrative, succeeded?
