I intended DAF, INTJ, and ENFP as acronyms rather than anachronisms. DAF is Direct Action Forum, the subject of recent exchanges. INTJ and ENFP are 2 of a set of 16 personality types in the Kiersey-Bates system, which would take longer to elaborate than I have time for; I wasn't expecting that to be intelligible except to those who have read the book. (It's one of those books, like Atlas Shrugged, that is pretty widely read in libertarian circles, and thus gets a lot of references that are cryptic to nonreaders.)
I admit my basis of comparison wasn't other political parties, of which I have no experience, but merely other social groups. If you haven't been affected by the issues I described, that's good news. It may also be true that those of us who have remained this long are pretty thick-skinned.
