Let the punishment fit the crime. Protect personal property. Protect personal liberties. Do not legislate personal behavior, opinion, speech, or beliefs.
It is only when those behaviors prevent others from acting upon their personal liberties and properties is when laws should be come into effect.
So you think not being allowed to take any bus, any cab or order a meal in any restaurant does not constitute an attack on your liberty? I wonder what the hell those blacks got so upset about in the 60s.
Who owns the bus, who owns the cab, who owns the meal? If I don't want you to ride my bus, tough. If I don't want you in my cab, tough. If I don't want you eating my meal, tough.
Get a clue.
