I wonder if Nimco Ali is also because she is good friends with Carrie Johnson? She is supposed to have gone and visited/stayed with Carrie during the winter lockdown I think.
I've had a look at the list now, and her name is just before Carrie's.
So I think that's it. To Lee, it apparently doesn't matter what else she's survived, and what positive impact she's made on the world, she's friends with Carrie. So bin it is.
I imagine that Lee would say, "but she is friends with conservatives/is a conservative" or whatever.
To which, I say, so bloody what. In general, the world is better when we do not descend into political tribalism, and instead, we work together on the objectives we share.
More importantly though, and also far more specifically, if Stewart Lee had ever stepped beyond party lines to find out about Nimco Ali and what she does, before throwing her in the bin, he would know that the left let her down first. Nimco Ali is a survivor of FGM and a campaigner to abolish the custom, and she has written and spoken frequently about leftwing politicians who characterise her efforts to eliminate FGM as racist! And who say that she is exaggerating the impact of FGM on girls.
