@Mojo, unless you want to modify your definition of Separatist I'd ask that you add a fifth category of "MoreExcellentWayist". I'm actually a bit vigilant towards malcontents and rebels--people who's primary motivation appears to be "agin" something. The better question is what are you for.
It's a bit "chicken and egg" or "two sides of the same coin", but my departure from the corporate church had more to do with pushing in where I saw God at work (an "in joke" plug for Experiencing God), which was mostly in my living room in small groups, on the streets of Houston doing worship evangelism, and in large prophetic conferences. What I saw going on Sunday mornings was ritual and good intentions, but I didn't see the power of God at work (see 1 Cor 2:4).
I believe "More excellent wayist" is a judgment call based on one's personal preference or experience. Each of the four listed might see their path as more excellent. You used a lot of personal pronouns in your evaluation of the situation. I'm not a strict relativist by any means, but each person has his or her own perspectives and experiences. Again, I say Grace is a beautiful thing, and allowing individual congregations and leaders of those congregations to pursue what they deem profitable or more excellent is fine by me.
I will concede that my separatist description was short. There could be Separatist A and B.
A) To hell with it, I'm gone and I'll crawl into my shell and complain.
B) To hell with it, I'm gone to serve Christ better than what I see available around me.
Better?
