Individuals who couldn't handle high stress environments can be weeded out individually. No need for a blanket ban on an entire demographic.
Think about women in the military. Women are, in general, less physically capable than men. But there are still women in combat positions, as some individual women can perform just as well.
Annoying Orange's tweets say they will not be allowed to serve the military in any capacity
See, y'all seem to be under the impression that "military" automatically equals "go shoot the bad guys and get shot yourself"
The reality however, is that "military" also includes tons of non-combat roles, such as nurses, cooks, maintenance, intel, IT, non-combat engineering, etc. Roles that will never see combat. Some of which never even leave the US.
To tell someone "you're not physically fit for combat, therefore you can't do those either" is silly
This is a very good point and I believe people are overlooking this.
As far as footing the bill, pecon also made another good point.
Either way, it's stupid to just ban all of them instead of actually doing proper screening like they are supposed to with anybody.
