I admit I only ever heard this term on MN in the past couple of years. Never really heard of it before then.
With the BLM going people, some people have been accused of virtue Signalling. I've heard it applied to other things/causes though.
I admit I'm pretty old school, and what I thought was caring about others and generally being a decent person now has a new name? What is the difference? I don't really know what my AIBU is but would like to understand when does it stop being about caring and start becoming about Virtue Signalling?
