You have the notion of “protected class” backwards. Everyone in this country has the right to equal protection under the law, but private companies are allowed to discriminate except in cases of protected class. AWS can say “we don’t want Parler as a customer” but they cannot say “we don’t serve black people on our platform” as race is a protected class while being Parler is not.
