That said, there's a huge gap between a religion a person is imparted with as a child, and philosophy they chose as an adult and have jumped into with both feet.
Many people come from backgrounds with bigoted ideas like that, but they don't colour their daily lives with it because they're not actively married to the idea - it's just part of the box of stuff they grew up believing passively.
This, on the other hand, is an active choice. An active decision that women are our lessers. That's far more serious. I have a lot more trouble with the idea of politely ignoring somebody who actively evangelizes this kind of idea rather than being simply passively being raised with it.
Where do you draw the line? How far do you go in ignoring the fact that key people in your community are, to be blunt: hateful?
Marvel Comics recently fired an illustrator for hiding Islamist, anti-Semitic and anti-Christian references in his art. His ideas were "normal" in his country - should that have been ignored? Reprimanded as long as he kept his politics out of his art?
