It doesn't seem like you are objecting to the term so much as the idea it represents. If the original poster instead substituted in the meaning of that term, e.g. if they said instead "This is taking insincerly aligning yourself with socially progressive causes in a trivial fashion in order to gain social standing while avoiding taking a stand on things that matter,to an extreme"* I assume you would still want to object? If so you should object to what they are saying not how.

*The term virtue signaling seems to be used differently by different people, so not sure if that was a fair substitution of definition.
