I don't actually think the problem is political correctness per se, I think it's more that so many people in Western Society are passive-aggressive, on all sides.
Playing the victim
Avoiding direct communication
Evading problems
Feigning compliance
Obstructionism
Canadians and Americans are both really good at all of the above.
If anything we need more political correctness. There is too much Homophobia present in the Military and people buy too much into an outdated concept of masculinity, when we know now from the science that gender is fluid and all gender roles are simply constructs of problematic western society (A systematically racist society).
Soldier in the New Canadian army need to be trained and informed of their misconceptions. Inherit biases, toxic masculinity etc. this is common knowledge at this point and many other institutions, government and other wise are already installing programs and training courses to make this happen.
Political Correctness is a politically motivated label, used in an attempt to hinder natural progress towards a tolerant society. Peoples backlash towards this probably stems from a fearful ego, white fragility or internalized trauma, that prevents mainly men from opening up and allowing themselves to show emotion and their natural feminine side.
Hope fully we get much more programs and restrictions/punishments put in place to help guide the Canadian military on the right path.
