"Flaw 1: Does your imaginary baker offer products with derogatory messages as a standard service? No? 

My imaginary Baker simply advertises specialty cakes. He doesn't have time or inclination to go into detail on every single cake he makes like it must be for a wedding or it must be for a birthday or it must be for the wedding anniversary of people named Jim and Sally or I won't bake it.. What Baker does?

Flaw 2: The government can't compel speech (political or otherwise). Anti-discrimination laws don't target speech, they target the act of discrimination against persons. There's a difference.

Yes...so If a skinhead wants a cake that says "Happy Birthday German Dictator..you're the best" That's not political therefore the Jewish baker must comply. That IMHO is wrong. 

"Flaw 3: The examples you give are not protected classes who are just trying to purchase a product offered by the business to everyone else."
