I agree with not putting up anyone because of their religion, but I really don't think there needs to be an exception made simply because someone who did great things did it as part of their religion. What about Fred "Mr." Rogers? I think some of his work on children's television has done more to shape the youth of this nation than many others. He did it as a Presbyterian minister, and even had a special commission from the church to do so, but he, arguably, had even less overt religious messages in his teaching than MLKjr did.
