The new chair of the America Conservative Union, which runs the CPAC, says that GOProud is too "aggressive" for his tastes, specifically referring to when GOProud's Chris Barron called ACU board member Cleta Mitchell a "nasty bigot" for being a nasty, antigay bigot.
The thing is, before they're against LGBT rights and women's rights and black people's freedom and full employment and health care, before all that, they're against anyone talking back to the powers that be. While conservatism in Western democracies takes on all sorts of issues depending on the context in which it appears, its fundamental goal is to establish, empower, and perpetuate an aristocracy. Hierarchy and respect as a one-way street are inherent to aristocracy, and Chris Barron and other gay Republicans and LGBT people generally are just supposed to take it without any back-talk. While the First Amendment prevents conservatives from banning LGBT people from advocating for ourselves (for now), they can control the people who want crumbs from their table.
