Yeah, that seems like exactly the kind of selfserving virtue signaling that makes the left look like a bunch of edgelords.
But I guess, it's easier to start such "actions" to feel like you're doing something than actually doing something. (not that I'm actually doing something, but I'm not pretending either)
In German, there's a relatively new phrase for that: Gratismut, free bravery. On the surface it looks "brave", but it's actually 100% riskfree and has no consequences whatsoever. But you do look brave.
