Harmful means something different to everyone

We can start by distinguishing between harmful and offensive.

• we previously had the examples like “your right to swing your arms stops at my face” or “can’t yell FIRE in a crowded theater” where words or actions were prohibited because they directly harm others

• burning the Bible/Torah/Quran/flag is offensive, NOT harmful. The relevant group you’re trying to piss off has a right to be pissed off, and you’re not immune from the consequences of your words, but no actual harm

• spreading falsehoods about vaccination leading to people avoiding vaccination causes actual disease and death. You’re indirectly harming others

So you can make the argument that we’re just making the same type of limits that we always had but adjusted for modern realities.
