// You have (deliberately?) missed the point.
It is racism pure and simply, and I am sure you would be shouting from the roof tops(quite rightly) if the other way round. Would you simply tell black people to go on another night? I hope not. //
I don't believe I am missing the point. I know where you're coming from, but -- I think -- it's from a mistaken position of symmetry. A minority group wanting one night to themselves, to discuss shared experiences from their point of view, is not being discriminatory towards the majority in so doing. When, as has been made clear, there are amply opportunities for the majority to join in, then that further underlines how manufactured the outrage is here.
The wider context is relevant. It'll go missing here, I'm sure, and I wish I could have a conversation with you about this on equal and respectful terms. But there's no shame in recognising that, on occasion, minorities might like a little time to themselves, and I'd encourage people to understand why that might be the case in ways that *don't* involve throwing accusations of racism or double standards around.
