Ah, but gender (and by extension, sexual orientation according to SCOTUS) is a protected class under the Civil Rights Act. Political affiliation is not a protected class.
For example, you could change your religion and it would still be illegal to discriminate on that basis.
I can decide to not say offensive things in a store so as to not be kicked out. But I can't decide to change my faith to be allowed entry to the store, because faith doesn't work like that. You can't force religious belief. At most, I could pretend to change my professed religion. But my faith remains unchanged and unchangeable.

They literally described what it's like to be a left coast conservative.
