I still read xkcd regularly and think it’s pretty good. I don’t think “we” as a community need to have a particular opinion of Randall Munroe or his work but personally I think he seems alright and I enjoy the things he makes.
Seems like a stretch to assume that comic does anything to recruit rationalists. If you’re not already in the rat pipeline it’s just a pretty good joke about probability and if you are, it’s still a better example of Bayesian reasoning than whatever the rats pretend to do.
I think “making up a guy to get mad at” is already an idiom as is.
