They've reached the final implosive stage of Libertarian Religiosity where each and every one regards themselves as the ONLY True Believer and every other person in their party no matter how insanely fanatical, no matter how cultishly devoted, no matter how dogmatically loyal, is a heretic. There can be no true Scotsman but them.
