The problem with the left isn't their goals. It's how they attempt to achieve them. Censorship, blackballing, blackmail and if given the chance concentration camps, secret police, Hitler youth, etc. These things are as bad or worse than white supremacy, sexism, etc. The most successful political route by far is enabling the most freedom for the most people possible. I think most Americans agree on this. Their problem is the method. You can't achieve freedom through repression of any kind.
