The Muslim Brotherhood looks pragmatic, but that's a tactic. Their goal is infiltration to directly challenges western thought. MB actively recruit Muslim intellectuals. Brothers use western ideological terms, such as democracy to lend their own definition to these concepts. The MB's stated goal is the conquest of the Western world by cultural means.
UPDATE: Entryism, the favourite tactic of the 1980s’ Militant Tendency, is when a political party or institution is infiltrated by groups with a radically different agenda. Since Militant’s Trotskyites were expelled from the Labour Party, the word has rather fallen out of fashion. But now, according to one Muslim leader, Islamic radicals are practising entryism of their own — into the heart of Whitehall – courtesy of a woman who was until recently a government minister. Baroness Warsi, the first Muslim woman to sit in Cabinet, handed official posts to people linked to Islamist groups, including a man involved in an “unpleasant and bullying” campaign to win planning permission for the controversial London “megamosque” proposed by a fundamentalist Islamic sect. He sits – alongside other radicals or former radicals and their allies – on a “cross-Government working group on anti-Muslim hatred” set up by Lady Warsi and Nick Clegg, the Deputy Prime Minister.
