While I know that members of the KKK are all inbred, cowardly, wimps that hide behind laundry, and are afraid that anything other than themselves and the extremely narrow views they hold is going to bring about the downfall of their back woods, self righteous, glow in the dark whiteness; I do support his ability to choose which way of life he feels is best.
However, if his apparent support of such a lowly and misguided organization is promoted beyond his simple KKK statement, then I think he should be banned because of the promotion of the anti-American hate rhetoric that the organization appears to stand for.
That's my view... and I'm glad I have the opportunity to express that in such a forum as this.
