If you read the Constitution Congress is prevented from violating 1st amendment rights. Doesn’t say anything about protestors. Protestors may be guilty of other things but not that one.
Peaceful assembly is also in the 1st amendment.
I sued someone for violating my First Amendment rights to free speech and assembly and won in Federal Court.
This person was not a member of Congress.
Wrong. Constitutional rights are for each individual. Congress can not make a law abridging any rights defined. I person or entity can violate an individual’s constitutional, God given, rights.
Considering its government operatives like in Chicago doing it and Government agents like the democrat parties violent thugs, its fully covered, We have the right to freedom of assemble and association and to petition for redress, all are protected from professional disruptor organizations.
Conspiracy to violate civil rights applies to civilians as well as government, see KKK cases.
