My $0.02 is that it's not a question of dedication, it's a question of ability. Doesn't particularly matter how much you want to do something...if you can't do it, then that's that.
For the moment, set aside social issues, sexism, chivalry, medical and hygiene issues, and anything else that I'm not sharp enough to think of at this moment. Any one of these issues would be enough to derail the entire experiment....but let's set them aside for now.
I'm sure that there are exceptions. However, in general, average women are not just slightly weaker, or less physically able than average men. They're catastrophically weaker, with less physical ability, size, muscle mass, and endurance.
Feminists can argue the issue all day. But, bluntly, you can't teach someone to be 5'10" tall and 180 pounds.
AFAIC, that's pretty much the end of the argument.
Very well put. I agree 100%.
