Yeah, if this was purely meant to attack bad faith usage of liberal identity politics, there are more clear ways to do it. Make it sound like a democratic politician somehow. This seems a lot closer to left punching, it's very much going "how do you do fellow workers, I also get annoyed by those activists and campus politics". It's not some sober analysis of how liberal politicians have abandoned labour, it's virtue signaling to people who get annoyed by certain type of language (which I've rarely heard in the past decade anyway).
