Gay wedding cakes, google and You Tube

Is gender a protected class? People seem to like to choose them frequently.

If gay is a protected class, maybe conservative could be a protected class too. I don’t see anything about either of them in the Constitution.

Sexual orientation isn’t in the constitution. It comes under the 10th Amendment and the inherent ability of States to regulate intrastate commerce. Sexual orienation protections appear under State law, not Federal. Federal Public Accommodation laws are based on Article I, Section 8 of the Constitution known as the Commerce Clause which give federal authority to regulate interstate commerce.

(DISCLAIMER: I support the repeal of Public Accommodation laws as applied to private business and the ability of customers to inform the public of businesses that have discriminatory practices.)
