Thanks for your response, Hector, but I still believe you have an obligation to speak out publicly. Keep in mind that the argument you are using ("nothing happened then when I complained and nothing will happen now") is exactly the same argument many people used when rationalizing not going public on clerical child abuse.

Posting a vague reference to a racist priest on a message board may provide you with a good outlet to vent your frustration, but it does nothing to get the guy out of the pulpit.
