By refusing to take part in the hierarchy of dominance you will eventually be subject to a more general and, frankly, human set of standards.
You mention some examples, like defending your partner from a mugger, calling out your boss when treated unfairly, paying for meals, etc.
Let's say a man stopped doing those things, what do you think the immediate and short term consequences would be?
What about: give the mugger what he wants instead of starting to fight him. This would keep your partner and you out of harms way.
There is also no need to call out your boss when he treats you unfairly. Just keep a paper trail and let his/her boss deal with the situation as it is their job.
There is no good reason that men are by default paying for meals.
I agree that those are sane approaches. I do think that there can be immediate unintended consequences. If someone didn't pay for a meal, there's propably less chance of a second date. Etc.
I imagine women went through similar consequences while entering traditionally masculine jobs and behavior.
What I'm getting at is that I think that we often think that this pressure is all in our minds, and to some extent that's true, but there are many stories of men opening up and being vulnerable and then their partners lose attraction. That's a hard sell to young men. "Yes, you will be alone forever, but it's necessary because in a couple of generations from now things might be better."
That mode of thinking only works if you assume all potential partners are the same. There are women who don't want, nor expect, the guy to pay for everything. There's stories of relationships getting better when men open up and women really appreciating that. Saying you'll be alone forever is not only a hard sell but also a lie.
Yes, that's a good point. And maybe sort of the reason I'm interested in these topics, is trying to figure out how to influence the social circles around me.
