By that, I don't mean be controversial for controversies sake (that's cheap). I mean that good writing has a point, and if you have a strong point people will be polarized by it, and that's actually a good thing. The worst writing I read (especially from myself) is writing that tries to hedge so it doesn't offend people. People SHOULD be offended. That's why you wrote the damn thing. If everyone already agrees, then you're not saying something worthwhile.
Plenty of proverbs would disagree.
Oh darnit, you got me.
