Sure. I understand the idea. But I'm far from being sure that such deeply shared requirement is addressed to only West guys as i'm pretty sure that East women are no more fundamentally strong that West ones. It is indeed all about social codes and constraints. In our still man man man world, I'm thinking about the issue seen by East women with East men . Internet is of no help, only caricaturing them as drunken illeterate bad boys . According to my own experience they should have a relative success in West dating sites full of normalized boring mens.
I don't think the requirement come from West (over?) femnism, it come from East own expérience of the modernity. So the question is are East men such unreliable and weak ?
