Isn't what happened today at the nation's capitol building proof that the Republican party is a bunch of violent thugs?

Yes we knew it all along. And it’s pretty pathetic that all these easily ID-ed maskless rioters today that are now potentially going to federal prison thought they were doing all this out of their ‘love’ for a President and a political party that never gave a sh it about them in the first place. Like when did the republican party actually ever give a sh it about people like these? The only thing it ever offered them was racist dog whistles to make them think they’d  be taken care of. Hardly. Maybe the federal prisons they’ll be going to will be more comfy than their little shacks or trailers or whatever. Who knows

We have known that for many years. Most are, not all. 

maybe you should start slowly.... use words whose meanings you understand, for example... 

No, it hasn't.  Some party members might be guilty of sedition and/or treason but all Republicans are not to blame.
