I mean, sure, the girl in the comic is super insulting. But obviously what she said wouldn’t happen in real life. Overall, the comic just feels like a mythical scenario (which is completely cool for a comic) that’s embracing toxic nice guy mentality (less cool).
Men can criticize modern dating. Any gender can. I’m not saying you can’t. The final frame in this comic portrays strong anger at rejection which is never okay. Sadness? Sure. Disappointment? Understandable. Anger? No. The anger signifies that you feel that the other person owes you something.
