If you think Nazism, a racist, hateful ideology opposed to the existence of many groups of people, is equivalent to being black in America, we have nothing to discuss.
If it becomes commonplace to discriminate against people based on their political ideology then we may very well see the 'political party' protection broadened.
The same way we deal with sexuality as a protected class, which is to say poorly but better than nothing.
> Should political ideology be a protected class?
I think it should, I wouldn't have said it was necessary in years past but it really seems like we're heading down a road where people are going to have to signal the 'right' political values in order to get hired.
In small doses businesses can refuse service to classes of people, but when the discrimination is so commonplace that it becomes a burden to those being discriminated against then you may see the creation of a new protected class (or realistically the broadening of an existing one) to make sure they aren't starved or unable to find employment.
