In practice, that is a horse of a different color. Should the Democrat Party and its Allies approve your agenda, one is allowed to assemble.
Should the Democrat and its Allies not approve of your Organization or its agenda, that is a different story. Then is when they send in their goon squad, members of Antifa, packed up by the police in with orders to break up your assembly and send as many of your participants to the hospital to be treated for their wounds. Should any of those assembled attempt to defend themselves or others from the attacks of the goons, the police will immediately descend upon them and swiftly and brutally subdue them. Just as the Germans did in the 1930s when the Brownshirts and Hitler Youth attacked the Jews.
So the Question of do law abiding Americans still have the right to peacefully assemble would be answered yes in theory but no in practice.

Yes, that’s the situation we’re in now.
