@LostInParadise Because being for establishment and against disestablishment are not the same thing. Let’s look at the example that gave us the word “antidisestablishmentarianism” in the first place. In that context, establishmentarianism is the support of making/keeping the Church of England the official state church of England, Ireland, and Wales. Disestablishmentarianism is a movement to separate the church from the state on the grounds that no religion should have an official position in the government. Antidisestablishmentarianism is opposition to disestablishmentarianism, but could have a variety of rationales. Some might think that a different church (e.g., the Catholic Church) should be the one in power. Others might think that the church should be separated from the state for reasons other than the disestablishmentarians put forward. And still others might think that it’s just not an important issue or that the decision should be kicked down the road.
