I put them in the Spiritualist, and or the Amillenialist category
As for me, I also see those who believe the end times in Revelation came and went and was never intended for 21st century Christians, as Preterits also.
These two views the preterits and the Amallenialists are quite interchangeable in things they believe.
Again, inside the 4 views, there are so many varying beliefs that it is very difficult at times to really nail them down to one basic belief. So it is also difficult to pigeon hole some into one viewpoint.
