Currently, there are these "trinity" related tags:
- non-trinitarian (29)
It's not at all obvious why the first four aren't all the same.
(If they aren't meant to be the same, their descriptions should be updated to make it clear what the distinctions are.)
Meanwhile, the last tag, non-trinitarian, is frequently used for a specific form of non-trinitarianism.
Trinitarianism is a belief that the godhead consists of 3 persons, and most usage of this non-trinitaian tag is directed to those that believe that the godhead is only one person (e.g. Jehovah's Witnesses).
This practice totally ignores those denominations that believe that the godhead is two distinct persons, and it leads to awkward questions (e.g. How do non-trinitarians interpret Philippians 2:5-8?).
It's questioning Jesus's membership in the godhead, but the use of the tag implies that those that reject the Holy Spirit as a member of the godhead must necessarily also reject Jesus as a member.
Many people might see nothing wrong with "If you don't accept the Trinity, how do you interpret Jesus's claim that he was God?". Nevertheless, that question is wrong.
Having a negative in a tag is generally not a good practice. (What would "non-African-American" mean? It would include Nelson Mandela, since he isn't American, but most people won't think of it that way.)
I'd suggest replacing all five tags with, say:
