I'd rather look at the merits. If I recognize a good idea, I'm going to signal that I'm on board with it, so virtue signaling in itself is, at worst, a bit gauche.

The reason I'd avoid making these things about social justice is that it's very hard to show that social justice as a concept actually works to promote comity. When you put things in terms of oppressor and victim, you deepen divisions rather than heal them. When you search for reparations and retribution, you have to harm people.
