How is Protection Against Discrimination Based on Gender,
Race, Sexual Preference, Age, Religion , etc, more
Important Than Protection for Political Views .
Coincidentally , I just stumbled on a 'wiki' , that includes Political 'Opinions' as a
possible 'protected group'.

Your political views are so important in fact that the govt says
that your voting needs to be in secret, that's a bigger step than
they take to treat the other categories mentioned, obvious IMV, that
political views are just as if not more important and deserving
protection than the 'said' mentioned.
A private company that is open to the public cannot refuse service
to the above mentioned , but they can shut you out if your political
views aren't inline with theirs.
Can you imagine the massive bich fits that would occur if you tried
to stop a Liberal from shopping at your store, refussed to
pubish their books, or twit their tweets?
