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.

Any annoyance I might have had at the "dog whistle" that is the term "dog whistle" goes right out the window when I see the group logic fallacy pointed out.

My entire life is "well sure, some boomers..." and "who specifically believes that?".

True, I really didn't need to use the term "dog whistle" there as the GP was pretty much outing themselves with the entire post. To decide that one entire group holds exactly the same opinion requires either a pre-existing distaste for that group or a complete lack of critical reasoning.
