As I have observed here before, post-1920 “right wing” had no meaning other than “opposed to the Comintern”, thus classical liberals, monarchists, Tories, Christian Democrats, nationalists of every sort, fascists, Nazis,. . . were all “right-wing”.
The multiculturalist globalist left has inherited the role of the Comintern, and now anyone who opposes their projects (be it pushing “gay marriage” down the throats of the populace of the entire developed world, deficit spending, anthropogenic global warming, coddling and excusing radical Islam, or whatever new enthusiasm seizes them tomorrow), whether out of a commitment to nativism, fiscal restraint, science, the Constitution of the United States, the Christian humanism of Dr. Martin Luther King, Jr., or any other cause is “right wing”.
