A number of sites, including Stormfront, promote white supremacy in general or espouse some amalgam of the philosophies detailed above. David Duke, America's best-known and most politically active racist, now spreads his slick white supremacist bile on the Internet. Concerned that the "non-white birthrate," "massive immigration" and "racial intermarriage" will "reduce the founding people of America into a minority," Duke boasts about the "genetic potential" of "our people," pointing out "innate intellectual & psychological differences" between whites and minorities. The site for White Aryan Resistance (WAR), a group led by San Diego-based white supremacist Tom Metzger, features unbearably crude caricatures of Blacks and Mexicans while applauding "racial and cultural separatism worldwide." Calling whites "Nature's finest handiwork," Metzger declares, "your race and only your race must be your religion." Fellow Californian Alex Curtis, creator of the Nationalist Observer Web site, attacks Jews, Blacks and immigrants, urging cooperation between "White nationalists, White separatists, Skinheads, National Socialists, Ku Klux Klansmen and Identity Christians." His "Tribute to Jewry" consists of a picture of "Jew York City" decimated by an atomic bomb. Other sites in this category include 14 Word Press, White Power World-Wide and The Occidental Pan-Aryan Crusader.
