This is a grey area and I'm not sure about this at all. Certainly not in USA. In the UK, I'm not duty bound to report an act of speeding, for example. Or someone smoking a joint. If I witness a murder, then probably I am obliged to report it, and probably should be. But even then it's a grey area. Often when someone gets stabbed in London, police are met with a wall of silence from witnesses. Even if the police know for a fact, and can prove, that someone was a witness, I'm really not sure they can compel someone to talk, because that person might rightfully fear for their safety. Of course the police can try to entice them with offers of protection, but rarely does it work.

The cake maker is claiming that by selling someone a cake, they are being "forced" to endorse gay marriage. I do not see how that is true.
Let's go back to a songwriter. If I ask for a song to be written to celebrate my gay marriage, then yes, I am asking the writer to endorse gay marriage. I wouldn't write a song about rape, even if I were paid a lot of money by a rapist to do so. I appreciate that analogy might be somewhat offensive, since rape is highly immoral and illegal, while gay marriage is not. But to a bigot Christian, gay marriage is immoral.

I mean... what if the flour mills decided they wouldn't sell flour to anyone who makes gay cakes - or anyone who buys their flour and then sells it to someone who makes cakes?
Is this an act of speech? Is selling flour to a cake maker "art"? The flour is not a unique product, it's not art, and so isn't protected by speech laws.
