I just watched a documentary called "Gay Republicans" about the Log Cabin Republicans and their debate over whether or not to endorse Bush during the 2004 campaign. If there is any doubt in your mind that the Republican party, as it exists today, is nothing but a huge cult then you should see this movie. It focuses of four LC members, three men and one woman, and their feelings about the Republican party, gays and gay marriage. I don't want to spoil anything so let's just say that by the end of the movie it looks as though there might be hope for two of them but the other two are two of the most obnoxious, loathsome examples of people who put party over country--and even party over their own civil rights--that you will ever see. I couldn't even watch the movie in one sitting, I thought my head would explode. Some of it was so bizarre that I almost suspected that it was a scripted work of fiction but it's actually one of those "Truth is stranger than fiction" things. A must see.
