You've qualified your statement that both genders CAN BE both, not ARE both, but CAN be, and further qualified it with "depending on the circs" (circumstances, I'm assuming). That indicates it's possible, but certainly not the case in all cases, meaning that not all men are strong in every instance, and not all women are weak in every instance, nor are they the opposite in every instance. So, it appears that you are saying that, sometimes, a women can be strong, and sometimes a women can be weak, depending on the circumstances. And that, sometimes, a man can be strong and sometimes a man can be weak, depending on the circumstances.
Kirsten Dunst said, "Sometimes, you need your knight in shining armor."
And you're offended by that. Highly.
