Left wing Do-gooders who believe that any diversion from their infantile world view should be countered not with reasoned debate or compromise, but with ad hominen attacks. Typically they silence discussion with epithets such as "racist", "sexist" or "homophobe" because they know that they would not survive long in a fair debate using Facts and Logic.
