I have four American-English dictionaries covering words for over 125 years. Only the most recently-published dictionary has dropped the word "pederast". Pederast means sex between men and young boys.
When I contacted my neighbor about this (Liberal of course—Wisconsin Academia), he ridiculed the use of the word. Even Howie Carr gave up after a few uses during the Velvet Mafia crisis.
Continuing to use "pedophile" where "pederast" is spot-on, will obfuscate this discussion forever.
Obfuscation is a prime tactic in the culture war. They want to think the homosexual priests prefer little boys to teenagers though the evidence shows otherwise. So like a good defence attorney they try to deflect the jury's attention from the facts.
