Yeah that’s fair. I work with some trots myself over union efforts, kinda impossible not to in the UK. I am perhaps overselling the position by overemphasising the historic conflict between the two. With that said I’m still baffled by the “I only mean tankies not communists” point. I can only imagine it comes from a place of not really understanding communists, or being deliberately misleading in that what they actually mean by “communist” is “anarchist” and that’s why there has been no further response.
