I keep on reading about virtue signalling as it is popping up everywhere and everyone seems to use it.

When I googled it, it came up with "The term is characterized by the signaler's desire to show support for a cause without actually acting to support the cause in question".

So what is it exactly? Is it when someone turns around and says "R U OK" when they really couldn't care less if you killed yourself or not? Is it when someone posts on Instagram about how tragic the fires are and then just goes on to not help out and gets back to commenting on how good someone looks in a bikini?

What is it? I guess the key bit is the bit about not actually doing anything about whatever it is that you are drawing attention to but suggesting that you are, but where do you draw the line? Surely people are allowed to feel sympathy for others but not having to always act?
