No actually. Consider the flip side, if another judge performed a normal marriage, should they recuse themselves because of bias on the normal side? How about Scalia because he’s Catholic? You’d have to find advocacy, not simply executing judicial roles.
I’m definitely believe marriage is as originally defined and intended but even having a gay judge is not enough to recuse because the flip argument could be used on a straight one.
Biased towards normalcy? There is *SUPPOSED* to be bias towards normalcy. It's called "sanity."
No, the converse argument does not work. Your theory hinges on the foundation that sickness and weirdity are socially and morally equivalent to normalcy.
