I would also hate to see a bunch of pacifists who, in the middle of battle, refuse to fire their guns....
And if the draft became compulsory for men AND women, guess how many pregnant chicks there'd be...and they'd just keep getting pregnant over and over until they were past the draft age.
But really, I was thinking I'd read somewhere that there's a higher percentage of spousal abusers and such in the military? It wouldn't surprise me. You get people into a group mentality, often a "good 'ol boys" mentality as the military is still mostly male (think of all the rapes you hear about in the military, not to mention the ones you DON'T ever hear about). Plus you have a profession that must attract those rigid type-A personalities who have to have everything their way, etc. etc.
(I've also heard people say that military wives are some of the worst breeders ever)
