Absolutely not. Discrimination should not be legally enshrined.

In addition, it would improve the quality of life for no one, but hurt the quality of life for many.

Then again, since a law as obviously discriminatory as this one would not pass scrutiny for Constitutionality, the only way to make it work would be to actually write it into the Constitution.

Good luck getting that passed, though.
The American people are far from perfect, but we are not quite THAT bigotted, thankful.
