Fair Play for False Prophets
By E. J. Dionne Jr.
NEW YORK -- Do white right-wing preachers have it easier than black left-wing preachers? Is there a double standard?
The political explosion around the Rev. Jeremiah Wright was inevitable, given Wright's personal closeness to Barack Obama and the outrageous rubbish the pastor has offered about AIDS, Sept. 11 and Louis Farrakhan.
After Wright's bizarre and narcissistic performance at the National Press Club on Monday, Obama would have looked weak and irresolute had he not denounced him. But if there was a moment of courage in this drama, it was not Obama's condemnation of Wright but his earlier and now much-criticized effort to avoid a complete break with his unapologetic pastor. .........
