This is a conservative site, dolt.
You, of course, overlook the possibility that eartick was being sarcastic.
So long as American nationalism was more-or-less identical to fidelity to the American founding, American nationalists were de facto American conservatives (that is adherents of the position that in Europe and Australia is called "classical liberalism", possibly with a tilt toward what in Europe is called conservatism). Trump has produced a version of American nationalism separate from American conservatism, and a lot of posters to this site favor that version. If you want proof, look at the more serious posts praising Trump for snubbing CPAC.
