The argument of protection, which I believe you two guys mean honestly, is also used as a strawman argument to hide the intentions to keep people out of the military.
I am pretty sure that this argument was also used when blacks were allowed to join the armed forces: "Oh, we gotta protect them from racism"
60 years ago at some boot camp:
"Hi my name is Bill and I'm black!"
- "Sorry guy, you have to leave the military, we have a strict don't ask, don't tell policy!"
