The last sentence in that little diatribe is key. The ACU - American Conservative Union, the organization that sponsors CPAC - is abandoning at least a "third" of the conservative movement. Todays Conservatism is made up of at least three branches, the libertarian/fiscal conservative wing, the neo-conservative/strong military wing, and the social conservative/anti-gay, abortion, euthanasia, etc. wing. Organizations such as GOProud and Log Cabin Republicans find themselves aligned with the first two but not the latter. In fact, the first two, back in the 1970's co-opted the third when they realized the power that could be gathered from the evangelical vote.
Social Conservatism also goes against everything that the first two stand for. The libertarian minded organizations in CPAC do not want the government involved in ANYTHING, must less espousing a social agenda that seeks to "protect marriage" from the evil gays. Thus, if anything, the social conservatives are the true anti-conservatives, not GOProud or the LCR.
As more and more social conservative organizations boycott CPAC - such as the Concerned Women for America, National Organization for Marriage, Heritage Foundation, etc. - we on the equality side should be rejoicing. The lack of bending to the social conservatives by the ACU and CPAC is encouraging, for it shows that these organizations are losing their clout in the overall conservative movement. Something any pro-equality person, conservative or liberal, should be rejoicing over.
