Having looked through his posts and subsequent discussion I must admit I can’t find an occasion where Roger has been told to “shut up or piss off” - I’ve responded robustly to a couple of comments (eg supporting Leave but not living with the consequences and things like branding judges “enemies of the people” because they rule parliament should be allowed the sovereignty that Brexiteers say they want to restore) and there was a spat with Carl (now deleted) where the “tea party” comment might have been.
The closest was this post by Dan Wood suggesting that Roger provide some evidence to support a claim of wrongful imprisonment for rape experience by someone Roger knew.
However there’s a good bit of distance between “Put up or shut up” and “shut up and piss off”.
