When did Traditional switch to misogynistic?

Growing up around my maternal grandfather who was very traditional and religious I've always had the idea of him being the true definition of a traditional man.

He was obviously born in the early 1900s, a war vet, a man's man but a father of three girls and two boys and a loving husband. He cooked, he cleaned, he took an active role as a father, he wasn't afraid of his emotions but was wasn't controlled by them, always told and made sure his kids knew they were loved and his wife was doted on. She had a career and when she got cancer he was never not by her side. She was his equal.

So this new version of what traditional is completely blows my mind. Was there a switch? My grandpa couldn't have been the only man from his generation who behaved this way and practiced what he preached, living and leading with love.
