Why is the height of a man so important to women?

It is the 21st century why do women give pathetic excuses like so I can wear high heals or so he can protect me. Why does the feminist movement like to pick and choose on this issue. If men started saying they would only date girls with a certain size the feminists would pounce on that condemning that but when it comes to men's height it is okay for women to discriminate.
