I'm not sure why you're surprised. Reddit has always been left leaning and progressive, and they were making a lot of noise about Trump his first term, especially with the Mueller investigation.
Now you have a huge trade war going on, he keeps threatening the soveriegnty of multiple long time allies, a billionaire has extensive access to government data (the same one that did that nazi salute), along with ICE being ramped up all in the first couple weeks of his term. Our president also ran a crypto scam that made him billions right before his term started. He also keeps joking about running for a third term and is challenging a 150 year constitutional law on birthright citizenship with an executive order. Even you have to admit that this is a lot going on compared to anything we've seen before.
I think that the issue with what's happening on reddit is that it's hard to know what's real or what's not. I think that there is a lot that this administration could be criticized for but the criticism has to be precise and targeted, such that most of the energy goes to the topics that are important.
A lot of comments and energy were expended there. Everyone talked as if it were the end of NATO and that the U.S. was abandoning Europe. In reality, it was just a 20% reduction in force (which was the first sentence in the linked article).
On the flip side, the trade war with Canada deserved heavy criticism—and luckily, it was well covered (I count that as a win).
From the list you just shared, I don't really have a good sense of the relative severity of each and I think it's because there is no place where these topics could be discussed (even HN isn't immune as you can see from one of the comments below)
