Maybe, but actually a masculine avatar is fine here. The whole thing would have worked just as well if, instead of "sweetheart", he'd used the term "nice-guy" as in the claim "nice-guys finish last."
I've seen that image of “nice guy” far more from MRA, PUA, and other anti-democratic than from feminists, despite having a lot more interaction with the latter.
See the niceguys reddit https://reddit.com/r/niceguys for the full flowering of this interpretation of the "nice guy" trope.
The guy who thinks that "being nice" to women is what gets them relationships + sex & that they're being wronged when a women rejects them even after they've "been nice" is definitely a thing.
