It's funny. From the days of chivalry all the way to the modern patriarchy, men's behaviours have been conditioned by one overriding factor: what will impress women? I don't see that evaporating overnight. Men suppress the emotions for the simple reason that women have demonstrated a preference for men that do that, and this is simply an example of that being made explicit. You could say "this is how the patriarchy harms men!". But it wasn't men who chose it to be this way.
