I'm going to say this simply, given my dating history. Any man who's a halfway decent person can find someone who will love them and ignore relatively minor physical issues (and sometimes major physical issues too). Any man who's complaining about not getting dates just because he's short has one of three situations:

1. He has the wrong social circle.

2. It has nothing to do with his height, and the prospects he's approaching recognize the red flags.

3. His own insecurities make it impossible for him to prioritize another person.

Of those, I have sympathy only for the first. Finding love is not easy for anyone, and it is possible to simply not know where to look. Otherwise, it's not about his height, it's either about his demeanor, or his own issues around his height.

My reason for wanting to be taller is extremely pragmatic: I need to be able to reach stuff in my kitchen cabinets without standing on the counter or getting a ladder. I need to be able to shop in stores without having to stand on the shelves to get stuff up top. Simple stuff. I'd also just once like to be able to see over someone's head in a packed movie theater, so that I don't have to choose between going only to shows that I think will have low attendance (matinees) or sitting so close to the screen that it's overwhelming.
