Lutherans vary from pretty tame to outright progressive, in my experience. They are also generally usually pretty tolerant.
you want to throw your hate on a particular denomiation, you should focus either on Southern Baptists-who have money, enormous political clout, and intolerance in spades , or the increasingly "non-denominational" fringe churches that made those everything else out there, no matter how nutball, look tame and reasonable in comparison.
