Who gives a shit, frankly. The first amendment is the first amendment, science or anti-science or anything in between. Whether or not I agree with anything in your comment.
Do you understand why you can't yell "FIRE" in a crowded theater? Do you think that's a violation of your first amendment rights?
No, actually, I don’t. Because you can. That’s not even the actual quote.
Sorry I didn't flesh it out.. Falsely yelling "fire" is not inherently illegal unless someone gets injured as a result. Millions of people died due to vaccine misinformation spread on social media.

At least millions, and that’s just COVID!

But the speech is still legal and protected. Maybe there should be more restrictions about these things, but that’s a case that should be argued in public and implemented the official way. Personally I think not, and instead we should be focusing on restricting the things that allow those ridiculous people making false claims to find the other ridiculous people that believe them.

Just imagine what Trump could have done during the worst of COVID with the power to restrict speech deemed untrue in the dark and without oversight.
