That's because, I suspect, you're too young to remember when it was perfectly legal to advertise that a job was only for men, and legal to pay women less for doing the same job "because they don't have to support a family."

Where do you get these "suspicions?"

I'll be 45 in about 5 months - old enough to know all about what you're describing. I remember hearing about and even reading about a few situations like that.

It's a black eye (no pun intended) to this country that it took from 1776-1863 to abolish something as odious as slavery, and even longer for women to get equal rights/equal protection under the law, (and even longer for men in commerce to have a sense of decency and justice towards everyone, REGARDLESS of gender, race, etc.)

The feminist movement has never been about "equality" or individual rights, at least nowhere near as much as it has been about groups wanting political power for purposes far beyond their stated goals.
