I tried replying to your comment, but I see you deleted it. This is an example of why the blockchain is important. Here, history can't be removed or rewritten to support a different narrative. Anyway, here's my reply if interested:

No one can critique opinions.

That's a pretty shaky epistemology. So much of what we some call "truth" is opinion backed by evidence. If we don't critique each other's opinions, how will consensus on what is be reached? If we care about rationality and truth, I do think we should actively and consistently critique opinions, starting with our own.
