Embittered Nice Guy logic is basically a downward spiral of blaming each new girl for the perceived cumulative failures of all the girls before them, such that each new girl is treated with steadily more suspicion and hostility than her immediate predecessor. This continues until one girl is held to be representative of all girls, at which point, the Nice Guy Singularity is achieved: he can now say that, because he was nice to one girl once, he has therefore, in effect, been nice to all girls always, even though his actual behaviour can best be described as a process of steadily escalating misogyny.
And when women point out that this is what’s actually happening, we’re held to be part of the problem. Because, at base, we shouldn’t have been allowed to say no in the first place.
Bringing this back because this is basically incel logic in a nutshell.
