I think this is taking what Martin Luther said out of context. He was a former Catholic priest, and lived in a country that hated Jews (Just think about the Holocaust, many centuries later). He also said he hated anabaptists, and I know today many Lutherans would be angry if you were baptized as a baby, then later re-baptized. But they don't HATE them anymore, anymore than modern day Lutherans hate Jews, unless it is cultural. (I work with two Lutheran pastors, and they are the most kind and loving people I have ever met - that is why they are chaplains, and so good at the job God has called them to do in long term care. And Lutherans where I am have set up 53 long term facilities, meeting a huge need for people who are not able to care for themselves. A lot more than I can say for my own denomination. And the cost is minimal, compared to other facilities!
Luther is a hero, in my opinion. He did know the Bible, translated both Old and New Testaments into German for the first time. He also brought the church back to "salvation by grace." No rituals, indulgences or intermediaries.
For that alone, we need to respect him, while recognizing he was not perfect, and some things he said were a product of the time in which he lived.
