Mr. Anchordoquy,
Feel free to start a public campaign to persuade the legislature to add "political affiliation" to Colorado's non-discrimination laws.
Right now, the Cheyenne Mountain Resort can refuse to accept business from either white nationalists or black power advocates (if the reason for refusing either group is solely because of their political views and not their race), or from Democrats, Republicans, socialists, communists, or the Milton Friedman or Thomas Piketty Fan Clubs.
If a baker refuses to make a custom cake for two women or two men because they are about to be married to each other while offering the same custom service to any heterosexual engaged couple without running a background check on their moral fitness, that's discrimination under the laws of Colorado.
If a baker was to refuse service to a conservative Christian couple because their religious views violate the baker's freedom of conscience, watch how fast the howls of protest from conservatives would arise.
