People who complain about "virtue signaling" are nearly always ridiculous. They try to deflect criticism of their own moral failings with vague insinuations of hypocrisy. They mock children for actually holding the values our society claims to teach them. They virtue signal about how much they hate virtue signaling, yet ignore that the most spectacular virtue signaling comes from their "side". Like this:

That doesn't make it a dog whistle. Everyone knows that accusing someone of virtue signaling is accusing them of being a champagne socialist.
