The kyriarchy leaves no mind untainted. If we examine our minds, our attitudes, we will all find biases, prejudices, stereotypes, stigmas, even self-hatred that is all coming from the oppression that we have been surrounded by from the moment our lives dawned on this world.
So what does that mean for us? On the one hand, it means that everyone interested in the cause of abolishing oppression can do a massive thing; challenge their own bias and oppressive ideas. That's hard, but it's also wonderful. It doesn't require grand gestures, or publicity - just introspection, humility and a willingness to apologise for and learn from our mistakes. On the other hand, it complicates everything massively. Most people we interact with day-to-day don't try to challenge their oppressive attitudes, and the old proverb about leading a horse to water holds firm.
