E. Stephen Burnett has a teaching about the problems with Patriarchy in a 5 part series called, Sins Of The ‘Patriarchs’. Interesting to me is that with all the words he has written about patriarchy, he never mentions spanking or harsh discipline. He does mention control, but not the physical aspect (unless I’m misremembering.) This would make it a good series to share with pro-spanking people.
He also wrote a book review of Quivering Daughters by Hillary McFarland.
I might as well mention that he also has warnings about Vision Forum on his site. He is worried about their possible influence on homeschoolers and he shares that he was homeschooled as a child. He has a very interesting site and it is well worth checking out.
