No, he's immune because he's BLACK, but Rand Paul won't say that.
Rand Paul, quoted here:
[B]eing a civil rights icon ... I would also say that that doesn't make us immune from criticism or debate. So, John Lewis isn't in a position where there can't be a healthy debate back and forth. Because he's a civil rights icon shouldn't make him immune. ... I should be able to honestly disagree with him, and not have it all come back to, I have no appreciation for a civil rights icon because of this. And I think that's the part that I think is sometimes unfair in this.
