You have the right to be heard by people that want to hear you.

Nothing says you have to be broadcast or promoted and nothing says you can impose on people who don't want to hear you, but the government telling people they can't talk to certain other people is not the same thing.

Also, in another comment you said "This is also great for hiding and suppressing organization of social uprising. This would have totally suppressed all the BLM content this summer."

Is this sarcasm and you are contradicting yourself or do you actually think it would have been great to suppress BLM organization and protests?
