Advocating means trying to persuade the authorities to make changes that you want.
Other people advocate for their point of view.
That's why we have elections.
If the religious people who want to force Christaria Law on the U.S. can PERSUADE the majority of voters to change the Constitution or replace it with their Bible ( which is what they really want ), then it might happen.
But a minority of a relatively few religious nut jobs cannot just declare that their beliefs overrule the Constitution and the Supreme Court.
Well they < can > declare that, but it would be worth just as much as me declaring my poop is made of gold.
If they don't stop trying to force their religion down everyone's throat they may wind up eating some lead.

Yet the court said this-
And it is ignored.
Finally, it must be emphasized that religions, and those who adhere to religious doctrines, may continue to advocate with utmost, sincere conviction that, by divine precepts, same-sex marriage should not be condoned. The First Amendment ensures that religious organizations and persons are given proper protection as they seek to teach the principles that are so fulfilling and so central to their lives and faiths, and to their own deep aspirations to continue the family structure they have long revered. The same is true of those who oppose same-sex marriage for other reasons. In turn, those who believe allowing same sex marriage is proper or indeed essential, whether as a matter of religious conviction or secular belief, may engage those who disagree with their view in an open and searching debate.
There needs to be a compromise where those who oppose have their rights also.
So in the same Supreme Court ruling they say Davis has the right to advocate as well as the Judge in Oregon.
