The 1A states that "CONGRESS shall make no law...abridging freedom of speech."
It also applies to state and local govts.
So, a college student attending UC Berkeley has 1A speech rights b/c Berkeley is a state school.
But, a college student attending Harvard, a private school, does not.
1. When Twitter bans or suspends a user for harassment, the 1A doesn't apply at all. Twitter is a private entity and so does not have to comply with the 1A.
You have no constitutional right to tweet.
Yes, NFL players have a 1A right to protest, BUT, that means Congress cannot ban kneeling by players. The NFL can.
According to a federal court, the answer is YES.
trump violates the 1A when he blocks people and prevents them from tweeting or replying to him.
We'll see how this question gets answered on appeal.
All clear? 😉
