Hitler was flawed but he was the last leader to point out stuff like disproportionate jewish influence, ethnic nepotism amongst jews and other groups, the corruption of democracy, the destruction of western morals, the dangers of communism and liberalism, feminism, the promotion of trannyism and 'p in Accademia, etc.
Every single person who criticizes him ends up unintentionally supporting a lot of ideas that are pure cancer. IMO you can say what you will about Hitler's solutions, but he was pretty spot on about the problems, especially with hindsight. The amount of times I have seen Jews talk about how evil white people are and how evil Christians are for no reason other than spite is evidence enough that his "antisemitism" had at least some reasonable grounds.
Of course, there are plenty of flaws within his system, but those never actually end up being discussed.
