Most denomination tags are in the noun form: methodism protestantism catholocism etc. And then there is evangelical which is an adjective. Shouldn't it be changed to evangelicalism? We would probably also need to create a tag synonym.
Many denominations do not have an "-ism" name anyway. Some examples that come to mind:
- Church of Christ
If, in the name of consistency, we had a mennonitism tag, it would be absurd. I think the best we can hope for in terms of consistency is to consistently use the term most commonly used to describe a given denomination, regardless of whether the word is a noun (such as the -isms) or an adjective (such as 'Mennonite' or 'Brethren') or a more general descriptive term (such as 'Church of Christ').
I'm in broad agreement with Justin and Caleb that consistency would be good to aim for. Unfortunately it isn't quite attainable if we standardise on "-isms" as "baptism" could mean the Baptist denomination or the act of baptism (or doctrines associated with it). Using "baptism" as a denominational tag would be very confusing.
I also agree with Caleb that an evangelicalism tag would be seldom used as most questions would (hopefully) be focussed on a particular evangelical denomination or would have a slightly wider scope (protestantism). It could of course be argued that protestantism is equally redundant as a tag for similar reasoning, but that's probably a subject for a separate thread.
Yes, I think they should be consistent. (And as moderators if this gets enough votes we can rename it).
However, "evangelicalism" is not a denomination and it is a very difficult to categorize word -- in my book it's nearly meaningless. I'm not sure what all should get that tag in the first place. I might argue that we don't have anything yet for which that is an important and definitive enough distinction to even have a tag.
