Frankly, I don't see how anyone can pretend there are any consistent principles at work in civil rights law. It's straight-up, authoritarian, social engineering, and has nothing at all to do with protecting our rights.
I am sure that the African American's of the 1960's would disagree with you.
The accounts they have of travelling from the North to the South in the 60's- and how they would map out routes to make sure that they didn't run out of gas far from a gas station which would serve blacks.
Mostly they gave up on finding public restrooms- since most restaurants and gas stations didn't have restrooms for 'coloreds'.
But I am sure there were literally millions of business owners in the South that objected to being required the 'social engineering' that required them to serve blacks as you are.
