Mark Twain said that faith is believing what you know ain't so. Well, political correctness is doing what you know ain't right. In every western country, Islamic extremists are allowed to exploit religious privilege for political ends by claiming to represent all Muslims, and the media always treat them as if they do. These groups give themselves official-sounding titles and talk a smooth line in community harmony, while doing all they can to prevent integration: to keep Muslims apart and ghettoised in a separate society, with a separate identity, separate rules and standards. In other words, they exist to cause division in society; to drive a wedge between communities that doesn't need to be there, any more than they need to exist as organisations.
