Not a woman, but...it's also possible that the reason they aren't actively paying compliments to men they aren't in relationships with is that a lot of men misconstrue even the smallest positive interactions as an invitation to hit on them.  

I'm all about normalizing the practice of free compliments between the sexes, but that normalization has to also mean that those compliments aren't invitations.

This is a case of the chicken or the egg. This thread will be filled with guys saying they have never been complimented and then women wonder why men assume that when they’re being nice to us, it’s an invitation, because it literally never happens to us. 

How are men supposed to solve a problem they didn’t create? If women all started doing it, it would be normalized but they won’t so men will never change because they only have the experience they have.
