I've mentioned a couple times that, so far as I was aware, no member of the Deaccession Police had had anything negative to say about the Baltimore Museum deaccessioning (to the point that I had to post my own tongue-in-cheek version of a response).
But according to this Hyperallergic post, there was one:
"Tyler Green, the producer and host of the Modern Art Notes Podcast, tweeted his concern that the BMA was not following AAM guidelines regarding deaccessioning, writing: 'It’s by a man, so we’ll sell it even tho it’s a great artwork.' A subsequent tweet read: 'I’d like to know where in AAM’s guidelines it says that deaccessioning motivated by gender is a best or even sanctioned practice.'"
