I argue it is pretty much implied in the title, isn’t?
People calling out the author for virtue signalling are doing exactly the same virtue signalling as said author on this message board by pretending there is a more correct way to behave.
In reality: people have opinions, and they can be different. That's fine.
The title is his opinion, you don’t have to follow it or even agree nor take offence to it.
