I'm not sure that virtue signaling is offensive, but is a deception, and at least highlights causes others can contribute to, even if the virtue signaler isn't always that charitable. The awareness of this particular habit of some just sheds light on a personality aspect, which is good to know about someone, but can also be understood an espression of low self esteem or insecurity, just human flaws, which can be observed and forgiven. It's pretty rare that all of us are as virtuous as we would like others to think we are.

I wouldn't worry until the virgins start lining up at the bottom of volcanoes. that being said, the striving for the perfect image of character is making me sick to my stomach. it's like being on a bus where everyones got on too much perfume and cologne.

It depends who the actor is socializing with. Forgive my torturing of a colloquialism but different strokes for different folks applies here.
