People do call him out on reddit, lemmy, and other social media. As for bigger names, it’s not just a matter of what’s true, but what the practical consequences would be.

Because Trump is so petty and vindictive, people tend to not want to say things that will tick him off. Foreign leaders might be of the mindset of “weathering the storm” in the hopes he’s replaced by someone better, while domestic media outlets risk being cut out of press briefings if they say anything critical of him.

As for the Democrats, they have all kinds of screwed up priorities. They’re constantly trying to appeal to the “center” and be accommodating to a fault. The right has criticized them for “promoting violence” when they do call someone a fascist or similar. They’re all about bipartisanship and you can’t really do that while calling the other side terrorists, regardless of the actual truth.
