Actually, rather than having issue with liberalism, he seems to be defending it. His argument seems to be questioning the "bowing down" to "authority". All "authority" - scientific, religious, etc - should be questioned and we shouldn't be "bowing down" to them.

Religion and science are not the same thing ( thought social science is far closer to religion than science ), but authoritarianism and appeal to authority are the same thing.

After all, "scientific authority" was the basis of white supremacy and nazism ( social darwinism ). It was "settled science" not too long ago supported by every scientific authority that white people were superior and non-whites are inferior.

You should feel bad for anyone who is a victim of censorship. Being happy that someone is oppressed because they don't align with your political ideology isn't any better than enjoying seeing someone suffer because they aren't part of your race.

And if you are a true "liberal", then you should be against "bowing down" to any form of authority.
