My argument is very very simple and very very direct Herr Barkmann.
1- current US law offers protections to people against discrimination and bigotry by making such actions illegal under US law
2- you advocate changing current US law so that one can engage in actions of bigotry and discrimination
3- you would enable and facilitate actions of bigotry and discrimination which are now illegal
And that argument is impossible to refute because either you do or you don't advocate these changes and you have already made it clear that you do.
