I voted for 'liberal', and quite proudly admit it here, but I actually identify more closely with the appellation of 'progressive'. 'Liberal' connotes a general air of tolerance, to my mind, while 'progressive' suggests a more proactive seeking of positive change in the world. I want the world to become a more enlightened, generous, and loving place for all its inhabitants.
Politics are necessary and inevitable in any human community, but I don't think they're the end all and be all of human endeavor. Solutions to human problems and challenges are never ultimately political in nature, but rather spiritual. When people make changes inside, outer changes will surely follow.
