I have thought about it and it is interesting that "virtue signal" is such a dirty word now. When I say "please" and "thank you" I'm essentially just virtue signaling that I'm willing to play nice
"Virtue signalling" implies a level of hypocrisy. Like, you don't really care about the underlying issue, and only cares in reality to look like you do.
When you say "please" and "thank you" you are being polite. You may be "virtue signalling" politeness when in truth you are an asshole, but I would be unable to tell, so I give the benefit of doubt.
By the way, I dislike the term "virtue signalling" as I think it was overused to the point of meaninglessness, and I have an issue with that. On top of that, sometimes performative actions do matter to call attention to a given cause. Things are more nuanced sometimes.
I just think it's an odd insult. I don't particularly like Discord, but I use it here and there because that seems to be the current replacement for what would have been private forums back in the day. I didn't think having that piece of garbage software installed would say much of my political positions.
