Not sure why virtue signal is being used ironically? Every political and social group is capable of virtue signaling. Plenty of folks left, right, and center who Virtue Signal their beliefs.

IMO, it's a useless term, since it's essentially saying, "someone did something they didn't genuine believe in", but there's little to no ability to demonstrate someone's actual intent.

Call people hypocrites (if that matters from you) or unauthentic.
