Is "women and children" offensive?

Seeing as feminists generally support men's liberation (not MRA, but genuine activism), I'm wondering what your thoughts are on this.

Personally I oppose it because war footage particularly from Gaza shows the emotional side of men and they caregive. I also think that on the Titanic, whomever was closest to the lifeboat should get in, not by age and gender. It also gives off the vibe that women and children are property or pets that men are obligated to defend, like a dog or a horse. What are your thoughts?
