Is patriarchy a bad thing?
Well, there does seem to be a need for some organization and control in society, although as I get older I question more whether anarchy is the super-bad ideology that we get told it is.
But - needing governments/armies/organized healthcare etc doesn't mean that it has to be white men in charge.
If you want to know if patriarchy is a bad thing, look at the history of Africa and the way that white men invaded and destroyed those cultures and countries, and created problems that still cause poverty, suffering and death now. Yet, we give ourselves such a big pat on the back for giving them charity.
Look at the one in four women who will be sexually assaulted at some point in their lives.
Look the % of men who are CEOs, politicians, the main breadwinner in the family and think about just how much control they have.
Look at my friend who was habitually raped by her husband for over a decade but doesn't see it as rape because he just persuaded her to let him have his conjugal rights.
Look at the four women every day (globally, on average) who are killed by their male romantic partner.
As distressing as it is, NOT seeing these things is even worse, because it means you don't even think these things are wrong.
