Fantastic question!
1) No, if I were *** I wouldn't want to force anyone to do business with me. In fact I'd take a considerable amount of pride in telling them to go to ****. Muslim ****.
2) No, we do not. The Constitution is fully sufficient to protect human and civil liberties AS IT IS. When people 'interpret' it to mean whatever the **** they want it to mean, they seek to undermine and destroy it--pretty much as *** and civil rights 'activists' have done for the last fifty years give or take. The Constitution contains the inbuilt means to CHANGE it to meet contemporary demands and ideals. It needn't be circumvented to achieve those demands/ideals.
Please note, however, that modern-day 'activists' don't give a **** about the Constitution or about a government limited by same. They seek domination. Much like Islamic and Christian fundies, they seek complete submission to their sick idea of 'justice.' And until the American people collectively tell them to go screw themselves, it WILL get worse.
