We are talking about two different things. I claimed that purging white supremacists from platforms is a good thing. I also claimed that silence is complicity. These are orthogonal. I am not a decision maker for one of these platforms, and don't feel the need to draw a specific line in the sand. Your attempt at a "gotcha" is fruitless, I'm afraid.
Let me turn it around, do you think that white supremacists deserve a platform?
