CMV: Compulsory military service creates a more homogenous society tolerant of differences within. via /r/changemyview

I come from a country which has a lot of diversity and does not have compulsory military service. A number of my friends come from places which do. I see the discipline with which they carry themselves. They are much more level-headed in their thoughts and actions, much more accepting of differences between themselves. I believe it comes from the training they received during their service.

In the forces, it does not matter (at least in theory) whether you were born rich or poor, black or white, gay or straight, man or woman. Everyone starts from an equal footing, and everyone has to earn respect by putting in effort on their part. People would still have differences among themselves, but when they're in the shit together they would be forced to put aside their differences and work together. Nothing can inspire camaraderie like serving together.

I posed this question already on another sub and was presented with a lot of problems which could arise. The economics, for one. Most large countries (such as mine) would not be able to pay for it. Secondly, the population is massive, so if all of them would be conscripted it'd already be 3 times the current strength of the forces. Some also said that having a combat-trained populace in an unstable country would be disastrous. A few others said that any military service of any kind promotes hatred and violence.

But none of these points were enough to change my view. I believe that at its core the idea is a solid one. Thus I would like to ask the community here to change my view, if they can.
