Yeah just did some googling on it and it seems he's part of the Cherry-sphere on that front. My local MSP, the "rising star" Kate Forbes, was a signatory to that concern-trolling letter a year or two back.
Oh yeah, I remember that. I'd rather have Forbes in leadership than Cherry but it's like choosing a glass of piss over a glass of diarrhoea.
In general I'm absolutely sick of the fake-progressives in Scottish politics who like to call themselves "left-wing" but who mysteriously seem to align with Trumpers and don't care about racism, antisemitism, homophobia etc. There was a tweet I saw recently from one of them saying something like "you're out of touch, most Scots agree with me" and I was just thinking, that's a bit fashy, isn't it. Minorities are just an inconvenience to that bunch.
Edit: And saying your politics are good compared to the Tories under Johnson. Bit like shooting fish in a barrel, isn't it? It doesn't take much to be more ethical than those shites.
