My 5th district Congressman is a Muslim, and I voted for him. His name is Keith Ellison and he is the only Muslim in Congress. How did he get there in spite of fear mongering about him being a terrorist? Because he is a liberal Democrat so it didn't stick. I saw footage of him speaking to a local mosque. He told all the Muslims there that gay marriage was just. He told them that since they didn't like prejudice - so they should not be prejudiced against others.
That's just a tiny bit about him.
