If he dropped out of Congress and became a talk show host, then I would have no problem with him. He's dead wrong either way, but you can argue against him as a talk show host. But you can't get him to represent you in government if he hates you. You think any Muslim is going to get a fair shake in Congressman Goode's office when he doesn't even think they should be in the country?
Finally, in the interest of full disclosure, I am sure I have said many things that many people found gravely offensive as a talk show host. Obviously, I have a vested interest in opening up the dialogue on-air. But I don't think this disqualifies me from the conversation. Instead, it gives me a unique perspective.
I know from firsthand experience that what one person finds valued speech is what another finds morally reprehensible. We have to let them hear all of it, and make their own judgment. Forcing people off the air and having no one but the most plain and unobjectionable speakers hold the conversation doesn't do anybody any good.
