The way I currently see this, it's treating Feeling and Sensing (and Thinking and Intuition) as going together, as opposed to treating Feeling and Intuition (and Thinking and Sensing) as going together - basically the clubs, which become a meaningful difference when you consider that duals are of the opposite clubs, but side clubs have no very good relationship (semi-dual being the best of them). So Democratic is anyone who is SF or has an SF dual, while Aristocratic is anyone who is ST or has an ST dual.

I don't think much of the Wikisocion description of this dichotomy... I think we had one on some thread that I liked, but it was of the "theoretical garble" variety.
