You are correct. Before Ronald Reagan and Rush Limbaugh, all the true conservatives in the country could have gathered for cocktails on the poop deck of William F. Buckley's yacht, Cyrano.
In fact, they often did! Now, condemned as "Paleo-Conservatives," it is quite understandable that their silken knickers occasionally get in a bit of a twist. I mean after all, "Who the Hell are all these new people in the club!"
Oh yeah, IMHO, they are also quite uncomfortable with actually winning elections.
Better advice has been given here: we should save our ammunition for the Left and not pick fights with other conservatives.
