Yes, there‘s a double standard, yes, I think we all disagree with it. The question was "Should a woman be allowed to do it if she‘s capable of doing the job". The question wasn‘t if they can pass the PT test, but if they can do the job. The CF doesn‘t need to go out and recruit women exclusively for the combat arms, but I don‘t think that fit, intelligent, capable women should be relegated to CSS simply because they‘re women, when plenty of unfit, unintelligent, incapable men are allowed in.
As anyone in the infantry can tell you, just because you pass the PT test doesn‘t mean you can do the job. Being able to do 19 pushups (male OR female) is NO determination of capability for combat arms. Yes, there is a double standard, I‘ve seen it personally on all my courses. No, there shouldn‘t be a double standard, especially where fitness is concerned... hopefully that will change. But along with the sexism, there is also ageism. So, (as mentioned previously) a 45 year old male will be doing an easier test than a 20 year old female, if if they‘re in the same MOC and rank. According to your argument, this must mean that he can‘t be allowed in combat arms either, right?
And as for "men can‘t walk around naked in barracks anymore," well if you were bringing a girlfriend or female relative to visit you in the shacks, would you want the first thing they see to be someone‘s hairy white a$$? Yeah, you need to wear clothes now... you also can‘t summarily execute people or beat new recruits senseless anymore. Do we want to bring that back too?
For hundreds of years people have said "In the good old days...." and said how much rougher they had it, how everything was better, the soldiers were better trained, better disciplined, and so on. So, we could go back to black powder rifles, wearing bright red into combat, have only white people of British descent who are 5‘8" or taller, and be able to flog soldiers for talking in ranks. Or... we could move forward, employ modern technology, weaponry and tactics, and employ people up to their abilities, regardless of gender, age, colour, or any other stereotype people care to mention.
As a freind of mine told me "Equality is when an black woman gets fired from a job because she‘s an idiot just as quickly as a white man would."
