You seem to be straying from any logical argument now and just projecting at this point.
1) User doesn't like the tags they have been given by other users
2) User proposes changes to the way tags are handed out
3) User benefits if/when they are no longer tagged in a manner they don't approve of
Seems to follow logically to me. Are you saying that doesn't sound self-serving?
1) I hit you in the face for no reason.
2) You propose I stop hitting you in the face.
3) You benefit from not being hit in the face.
Is your proposal self serving? I would say so. Is that wrong or dishonest? Seems like a stretch at best. In summary you are literally using the fact that I am being attacked to discredit my objections to it. You know what that is called? Circular logic.
