Because you only advocate for ideas that dont exist in reality, and deride actually existing marxism as 'tankie', you can continue to advocate for idealist positions, but it requires you to build a coherent movement around it otherwise its just masterbation and contrarianism.
Your position is idealist and neither rational nor good faith - don't expect others to meet you with merits your position lacks.
I don't see how acknowledging that other branches of communism and Marxism exist is idealism, bad faith, or irrational.

That's not what you've done, though, is it? If you're unable to describe your own arguments, how can you possibly hope to engage with other people?
