From Barcepundit:

SELF-HATING AMERICANS: "My experience shows that almost all anti-American prejudice in Europe is based on stereotypes that the Europeans get from leftist American political and media sources," John Aust writes. He translates an interview with Lynn Margolis in a Barcelona newspaper; don't miss his comments. He ends: "And, Ms. Margolis, let me give you a hint: The Europeans believe that BOTH red-state conservatives like me and blue-state leftists like you are EQUALLY ignorant, backward, and mentally primitive. You're not impressing them."

Perhaps more "reinforced by" than "based on." But it's certainly a factor. Be sure to follow the link to John Aust. He's a revelation to me.
