Here's a quote from their site:
" ... there are Unitarian Universalists today who cannot accept that many of Marx’s economic philosophies have been disproved by the science of economics. Like creationists, they cling to the philosophy in spite of overwhelming scientific evidence to the contrary. Whether it be a hard core Marxist agenda, or the more common soft-core versions of Marx's agenda that is so prevelant in so called Liberal circles today, many UU's continue to promote the Marxist ideologies in spite of the overwhelming evidence that they are not just failures, but spectacular ones."
Man, gotta love THAT!
