Well, one time my kid said some misogynistic shit (it's been a decade, I can't remember the details) and I spent 10 or 15 minutes chewing him out in front of his siblings about how that's inappropriate and wrong, with examples of the errors and results. When we were talking one time after he'd reached adulthood, he told me this turned him away from the path of radical anti-feminism.

No guarantees this will work in most circumstances, but it did this one time.
