He's got Maureen Lipman on his In the Bin list, as well as Darrell Maclaine, who is a small time actor more or less just starting out in comedy, who seems totally innocuous as far as I can tell. Maclaine has a channel on You Tube (TV Themes Go Pop) where he posted short songs during lockdown of pop singers singing TV themes, like Paul McCartney singing 'Are You Being Served?'. Quite funny. Can't imagine what he has done to deserve being on the list.
He's also got Nimco Ali on the Bin list. She has spent years campaigning against FGM and supporting survivors.
I've never found Stewart Lee funny, but comedy is subjective and some people obviously do. At least he has Barbara Nice on the Pedestal list - seen her Raffle show a few times and she is very funny, without being snarky.
What I love about Mr Lee is that I can disagree with some of his political comment, but still find him funny (and I do broadly
align with his politics, as it happens). Most of his humour is more subtle than simple party line stuff, much of it isn't political at all. 90% of his act is about the meta, or putting himself down; he is almost always punching up, and the joke is often him being bitter about someone more successful (or younger), poking at them with his nasty "so-called jokes".
Almost no-one will think Mark Steel doesn't get this. A lot of the tweets on that thread are more ambiguous, which is how Lee would want it, I think. I hadn't even seen the whole list, but could still enjoy the bantz. It all gets so self-referential that it's impossible to take offence; even a few of the comments here ( https://www.stewartlee.co.uk/online-critiques/
) are clearly ironic call-backs to Lee's own routines.
( If you really want a spite-filled, right-on, leftie, unironic Tory-hating routine, go watch Alexei Sayle. He's very funny, but I don't see the point of some of his rants; still, they went down a storm with his regular crowd! )
