I've seen quite a lot of analysis recently (of Woke more generally) which has come to a similar conclusion.
If you're someone who finds it important to be liked, you are going to be much more susceptible to going along with nonsense if it becomes fashionable. Someone clearly bolshie and bloody-minded, used to being disliked by some, like that character Stuart Campbell, is not going to give it the time of day.
His level of commitment is impressive though - the nonsense clearly offends him at a visceral level. Or I guess it's maybe his anti-authoritarian instincts kicking in - he has more scorn for the people using the nonsense as a means to power than for the nonsense itself.
Two of my other favourite old-time (remember Iraq?) bolshies are Andrew Sullivan and Glenn Greenwald. Been interested to see where they were. Sullivan is happily 110% GC, loudly.
Greenwald is taking his time, but he seems to be getting there - he was taken aback by the attacks on his hero Navratilova, and wrote a long article about that, and he had a sane video discussion about the ridiculous Spotify employees-versus-Joe Rogan & Abigail Shrier thing. If he doesn't ultimately go full GC, it'll be a sign he's gone soft.
PS here's one of my favourite pieces on the theme by Louise Perry:
Are Contemporary Feminists Too Agreeable?
