Turns out we don’t need to go by what any one person “wants” because the law actually allows for deportation in the case of visa holders who support US-designated terror groups
If someone states their support for a terror org on their visa application it can and should get denied (non-admittance). If someone starts supporting the KKK after they arrive, they can and should be deported (revocation).
It’s actually a smart solution if you think about it. Why would we import KKK en masse? What on earth for? To what end?
