I apologize; while reading the thread on my phone, I thought you were responding to me, but you're not. I'll still respond, though.
> I believe you are sincere. Sincerity has nothing to do with virtue signaling.
Virtue signaling is about intent. Honestly stating a genuinely held belief because you believe it and want to communicate it is not virtue signaling.
In your response, you're making an assumption about the person who wrote the comment. You're assuming that they wrote the comment "so we'd all certainly know what a virtuous person you are." But that's your assumption. You don't know that.
So why are you making that assumption? People often extrapolate their own motivations when judging the behavior of others. That's why I'm suspicious of people who accuse others of virtue-signalling. It conveys something about their inner state and their own motivations.
