I disagree that Roderic here is trying to alienate and dived. I see criticism that must be taken into account discussion of discipline among communists and what is to be done is not Left deviation-ism. In the first tweet Roderic is referring to the fact that the building of the vanguard party should be the objective of the communists and that the discussion's around other method's should be subordinated to that goal. Although his American comment is perhaps uncharitable I can see that. The second tweet is more controversial I suppose Roderic expected more of a higher standard of discussion out of this forum then he observed (since it is dominated by communists) As this forum is not explicitly a Marxists theory board I do not share in his disappointment as much.
