“Don’t think so! Private business. Where’s the necessary involvment of the State. We all discriminate in one way or another. It’s not illegal. But it is for the State. No State action, no discrimination.”
1950’s. Blacks sitting at lunch counters in the South even though the owner had told them to get out. Lawsuits result. The rest is history as we say.
Those were private businesses; your first point. The state was not involved; your second point. We all discriminate..it’s not illegal; your third point - it is illegal. The Supreme Court ruled just so.
The 14th amendment is directed to the States, not to citizens in general. But then I guess all these fellow freepers who are trying to set you straight could be wrong and you might be right.
