Lefty types, feminists included (perhaps more so than most, as they don’t have as much victim cred), seem to have a compulsion to virtue signal; that is, make a big show about how they have the correct values with respect to what ever topic is under consideration at the time.
Have these correct values been arrived at via careful consideration? Probably not. Have they considered to cost and potential future implications of these correct values? Yes and no. Yes, they personally gain status points with their crowd, and no they do not consider much of anything else.
One could view it all from a pride perspective. One can feel pride when one accomplishes a task that was challenging, rare, and/or useful to yourself/others. Does this criteria apply to virtue signaling? No. But still there is pride, a very empty pride. Probably most virtue signalers know the score, which make them very sensitive to being accused of such.
Contrast this to the historical Christian perspective. It was expected that Christians would do good deeds beneficial to people, and to be modest about it. The idea is that the deeds are more likely to come from the heart. Furthermore, potential resentment among others is reduced. Naturally enough, the virtue signalers are the antithesis of this, with their puffing up the deed of having the in-fashion views. Perhaps they are oblivious to the resentment they cause.
Short answer — society would be a much improved place without virtue signaling.
