Heck you can say Hitler wasn't all bad. He brought Germany out of a depression that was worse than America's, rebuilt the nation in three years into an industrial powerhouse, hosted the Olympics in 1936 with the first modern games that set the standard ever since, and was Time Magazine's Man of the Year in 1938. Stalin wasn't all bad, either. He brought Russia out of an archaic agrarian producer to becoming heavily industrialized and modern through the 30's. This helped Russia defeat Germany years later since they had the industrial capacity to produce tanks and other weapons. Of course you know the darker histories better.
If you want to smooth over the negatives it can be done. But we tend to look at what is most notable about leaders. trump was highly indifferent to the job, was incompetent, was highly corrupt, and did very little that actually helped the USA progress. His immigration policies were criminal. He actually had an easy time as president until he had to face emergencies in his last year, and he failed miserably at these challenges. There's a reason he's ranked among the worst in history. Biden is not perfect but he is experienced and has had a lot of things on his plate his first year. Trying to put the government back together, and having lost time in the transition put us back a lot. His first priority was the vaccine to defeat the pandemic. And then work to support the economy. And then work to get infrastructure investment while he has a congress to pass it. And then Afghanistan turning ugly fast, which was more of a military failure than on Biden. The right has really mobilized in the USA and they are sabotaging efforts by the democrats to get the nation vaccinated, protecting voting access, helping the economy, and now this anti-abortion nonsense which is likely due to the supreme court being so conservative thanks to the three justices that trump picked. Republicans did support an infrastructure bill that after the long list of natural disasters happening there is a serious need for rebuilding it. Republicans are resisting more investment, and that will only hurt the future of the USA because we have serious problems that will cost more in the long run due to responding to the emergencies, and the lost times the public will be suffering the outages and destruction.
