I said that it wasn't coercion, that doesn't mean the inverse is also true and it does not mean that it was ethically right.

I addition, what stops me from saying that what you have said is your subjective opinion?

I do believe in freedom of speech and that it should be protected and the it is quite likely that the gay couple sought out trouble for attention which they should not have done.

However, he still doesn't have a right to deny service (or suggest alternatives etc.). As requiring someone to complete a service for payment is not the coercion or prohibition of speech or expression. Ideally, we wouldn't have any reason to have this conversation if the couple had sought to avoid trouble or if the baker hadn't held preference or whatever variable you wish to change.

How is this a meme?

His service / product is the creation of his artistry in the form of cake, and they were not asking him to halt his creative expression, they were asking him to continue it for a particular purpose, thus there is no right being violated

also displaying an image of blatant situational bias does nothing to help your credibility

There is no problem here with freedom of speech

The problem is as I stated, his right to deny service, which he does not have, freedom of speech is not the same thing as the right to deny service
