Thus far, no one has suggested that all the trots, anarchists, MLs get together on the ground in my area,

What does "get together" mean? How does it address organizational, structural, ideological, strategic, and tactical differences between different factions?

If you simply mean "talk to each other without spitting in each others faces" that already happens more than plenty among the more mature members of different factions thatve been in the game for long enough.
