No, I think you're missing the point. In this tumblr, the guys describe themselves as being "nice", that they're worth going out with, etc. but when you look at the rest of their profile, they're either misogynist, homophobe, so maybe not what we usually understand when we hear the word "nice". For instance, there's one profile where a guy says about himself that he respects women, that he doesn't understand why women don't date him, but later in his profile you'll read that "there are circumstances where women are obligated to have sex with him" or that "men should have the lead in the relationship". So basically the tumblr points out the contrast between what the guys want to show and what they're actually showing.
