“Should judges who smoke be barred from tobacco cases?”
Not a correct analogy. Smoking is not currently illegal while homosexual marriage IS illegal in California. So you have an avowed and unrepentant sodomite judge who is presiding over a case on illegal same-sex marriages. It’s full stop insanity.
Homosexual marriage is illegal. Homosexuality is not.
Your logic says that a Christian judge should always rule in favor of Christian churches.
An honest judge would rule according to the law. Period.
