You seem sincere but confused. Or maybe there is a difference in terminology. Liberals as I use the label are a group distinct from the Progressive Leftists. Liberals believe in free speech even if they don’t agree with it. Progs believe in forcible suppression of politically incorrect speech. Liberals believe in fairness to individuals, in judging people on their own merits. Progs believe in identity politics and imposing quotas anywhere they can. True Liberals are deeply opposed to the authoritarianism that is the essence of the Prog agenda. I think most of what you resent is not Liberal at all, but Left Progressive repression.
