The reality is that every society puts some limits on speech, and vast majority of people understand that free speech absolutism isn’t desirable. So, the real question is why people think that the limits on free speech that western liberal societies decided on are inherently correct?

This obviously a chauvinistic position that westerners tend to take because they suffer from the anchoring bias of having grown up in a society with a particular set of rules that they’ve internalized and now treat as the natural default.
