I see your point, but I'm already confident in my ability as a provider and protector. So for me it isn't a matter of being undermined or demasculated in some way. My actions will always speak for themselves. I'm not fragile enough that if a woman put her arm around me at the movies or held the door open for me I would start questioning my manhood. Lol.
It's ok if some guys need to assert their male prowess via door-opening, not receiving flowers, or having an arm put around them. Those things seem surface level and superficial to me. A true test of a man is being able to provide and protect when it really counts, not split hairs over a door or flowers. That's petty and actually shows a weak man in my opinion.
