On a slightly different note, for those of you in the sociology field - my area of interest is conflict, and particularly the way in which community- or grassroots-based conflict resolution programs [dialogue groups, etc.] can have an impact on wider peace-building efforts, or, more generally, how they can affect society at large. I'm particularly interested in youth-based programs
As others have suggested, check out the peace & war section of ASA. If I'm reading your interests correctly, it sounds like you may want to look into Applied Sociology programs as well. Also, check out programs that focus on Community & Urban Sociology.
And to back up what others said, I've seen plenty of students do well w/o a BA or MA in sociology (and plenty with BAs in soc do poorly). My BA wasn't in sociology, but I came in to our dept at the MA level.
