You can use Michael Phelps as an example, then. Or any other swimmer you think has a better face than this one.
The point is that the swimmer's body type is the most attractive one for women. If you aren't short, you'll get better results in making yourself more attractive by pursuing it than by getting CLL.
The point the man in the image I posted has reached means that there will barely be any woman who would reject him simply based on how he looks. Only a tiny, tiny minority of very insecure 178cm+ women. Not being rejected based on how we look is something most people here want. Just being a decent height and getting a good body will allow you to reach that status with the vast majority of women. You won't get immediately rejected because of how you look if you look like this. It'll be other factors.
Still this is your opinion.
I showed him to my gf only asking him if he good looking (without mentioning his height) and she said he is ok, not ugly but not handsome either.
So no, not only a minority would reject him and not only for his height.
So saying things as a fact while it is only your personal opinion is not very clever.
The fact is that men beyond average are not as attractive as above average, all other things equal. Yes, at 1.75 you have a respectable height and if you are fit with a good face you are not going to have many problems with maybe the majority of women.
That said, if you have all the above and an 1.85 height you'll be exactly what any woman wants. So yes, being acceotable from the majority of women to being almost ideal for the vast majority of women has a big difference.
And almost no man with an 1.75 height is ideal for the majority of women, even if he is perfect in anything else in his appearance.
