Agree. All male armed forces would be perfect.
I don't agree with that. There are a buttload of jobs in the military that, frankly, are being done by lard-ass males with zero physical ability. Plenty of ways that women can (and do) contribute where the physical differences don't come into play.
There are legitimate arguments about MOS restrictions, but just as one example, there are "cyber-warriors" in pretty much every branch right now, and there is no earthly reason to exclude women from those positions.
