Otherwise progressive people in my country (which has mandatory military service for men) tend to lose braincells when I mention that it's sexist to only force males to do military service.

Literally ever reason they cite against female conscription is sexist and based on outdated stereotypes.

a) "Women give birth, men do military service, everyone has their role". That's bullshit. Women are not forced to have children nowadays. Men on the other hand are very much coerced to do military service.

b) "Women would get sexually harassed in the military", and weaker males get horribly bullied in the military but nobody seems to care.

c) "Women have periods", are women equal to men or not?

Then they hit you with "mandatory military service shouldn't exist for anyone", which is bullshit because banning it is a completely unrealistic scenario right now and they know it's not going to happen.

Male only military service is SEXIST.
