Being opposed to kingship remains an easy test to pass.
The issue is not being opposed to kingship. The issue is that people can't agree about the facts of what is happening on a day-to-day basis, so they can't agree on whether there is a king.
Everybody is opposed to kingship. Arguing about that is pointless. Or worse, it's used to promote bad things.
The disagreement is in who is being a king, factually.
