This seems like a reach to me. People are allowed to have preferences and it's okay to have a physical trait as a deal-breaker. Like, what if a guy absolutely loves girls with huge butts? Am I going to call him shallow or insecure if he refuses to date girls with flat butts? No. I might think he's limiting his dating pool a bit, but that's his choice, isn't it? As long as he's not cruel to women with flat butts, then he's free to have whatever he wants as a deal breaker. And if he meets his dream girl but she has a flat butt and he decides to let her go because he just can't jive with that...well, that's his choice. I may consider it his loss, but he still has the right to do that.

Also, there are very few women who would find their literal dream man but reject him because he's a few inches too short. If that happens, it's usually when she's in the beginning stages of meeting the man, and in that case...she doesn't really know him anyway, does she? If she gets to know him and he's her literal dream dude, I assure you, most women would not randomly just toss the dude aside because of height lol. Women are not mindless robots; if they develop feelings for a man, those feelings aren't just going to be easily cancelled.
