Read the constitution.
14th Amendment and all that nonsense.
Have a nice day.
Moving on. . .
So, if they passed an amendment putting people in concentration camps, that would be constitutional?
If the Founders had wanted the government to force businesses to serve customers, they would have mentioned it, heck they probably would have just stuck with Britain. Like the prohibition, this amendment was full of BS and it actually laid the groundwork for Roe V Wade.
Supporting the concept of government dictating who businesses serve is a communistic view. Have you signed up with CPUSA yet?
