I read your posts. You started with "He was ridiculed for it because it was only a partial ban on China, put the focus solely on them, and did nothing to restrict travel from other countries." That is the portion is was addressing.
I personally think Trump is an asshat. I just also think he gets blamed for stuff that he shouldn't be blamed for, and doesn't get credit for stuff that he deserves some credit for. The opposites of those two are also true (takes credit when not deserved, and ducks blame when it is deserved). I don't think he deserves credit for the development timeline of the vaccines, just as I don't think Biden deserves credit for ramping up vaccinations.
I don't personally think that any other person as President would have had a big impact on how many in the U.S. got sick or died. As has been seen, the virus is going to do what the virus does. Americans are what they are...stubbornly resistant to being told what to do...and fat. Our nation is fat and unhealthy. Could we have done better? Of course, but not drastically better, and at a bigger economic cost. I personally believe that many people want to blame Trump as if he somehow caused the virus or most of the deaths in this country, but they really have convinced themselves of that because they hate him, not because it is true. It is undeniable that his messaging on the pandemic could have been much much better. He says stupid shit, and in stupid ways. It is also undeniable that many in the media and those who hate him because of politics sought to label his every move as racist, moronic, etc., when they really weren't. His statements have always been intentionally twisted, taken out of context, or intentionally misquoted. It is what it is.
