Hypocrisy has been defined as "the tribute that vice pays to virtue." The question of who first defined it as such is a good one. The first three results that Google gives me are Grover Norquist, John le Carré, and Peter Singer. Since GK Chesterton was familiar with the sentiment I think we can answer "no" for all three. Quotes frequently become disconnected and float freely in the cultural ether, but this post isn't about that.
The term "virtue signaling" is generally thought to be a similar thing to this meaning of hypocrisy. But I think it's more insidious than that, which is why it bothers me. If what vice is paying tribute to is actually virtue then there's an ideal that's being held up, even if falsely. But―and recent events have strengthened this belief for me―I think that in virtue signaling the things that people want to attach their names to aren't really virtues. They're just things that society is promoting at the moment, and might actually be evils.
Of course this isn't new either, but it's important to see it for what it is.
