After consulting the very WP:MOSDAB, there should be two articles, "Fraternity (disambiguation)" and "Fraternity". "Fraternity (disambiguation)" should be links only. "Fraternity" should be an article that applies to all fraternities of whatever kind. So, I am going to follow the wikipedia policy you suggested, AND not wait around for consensus. Any whiners can post complaints at WP:MOSDAB129.133.124.199
