Lansman might have kept out the old Militant Tendency mob but they were discredited already and past their SBD. But by insisting that Momentum comrades had to be members of Labour then that just legitimised them and give them licence to infiltrate Labour from within. They started by stitching up the NEC.
It's called Entryism and has been a classic Marxist strategy for decades.
As for the Momentum identity, they have a dedicated logo/icon/flag identity which his different from Labour's.
PS - are you and Cella one and the same or just joined at the hip?
