The Navy has relieved Lt. Cmdr. John Sharpe of his assignment as public affairs officer on the aircraft carrier Carl Vinson while it investigates charges that he heads two anti-Semitic groups. The Virginian-Pilot reported yesterday that Sharpe leads the Legion of St. Louis and IHS Press. Sharpe said he founded the Legion seven years ago as a Web-based forum for discussing Catholicism and contemporary social and economic issues, but the forum is now inactive. The Legion's website says the Legion's goals include combating "the Judeo-Masonic tendencies of the modern social order." Sharpe says that secularist thinking by "liberal Jewish" groups and Freemasons keep "political and social life very separate and distinct from any faith-based approach." Navy regulations prohibit personnel from participating "in any organization that espouses supremacist causes."
