If it's illegal in that specific jurisdiction, then steps definitely need to be taken to ensure that.... But a lot of the time, at least in my experience of looking at content moderation, it's not so much about legal or illegal; it's more content that creates a certain atmosphere, and the challenges of that certain atmosphere chill speech and make minorities, different genders or people with different sexual orientations much less comfortable speaking, and that impoverishes the public sphere.
We live in a world, right now, where there is a real challenge that people who are important parts of our communities no longer feel comfortable debating things on the Internet. I don't think just saying that it's identical to media will fix that problem. There is a huge challenge on how to restore a space where people genuinely feel comfortable having a public conversation. I think that's a huge challenge but an extremely important one.
