Joe,
re: "it is so sad that the bishops are so concerned with these issues when they, for years and years and years, covered up or ignored the pedophelia scandal among their priests."
Your reasoning is flawed.
While it is sad that the bishops "covered up or ignored the pedophilia scandal among their priests," horrifying in fact, that colossal mistake does NOT reflect upon the validity of their current concern. It is unrelated.
Logically, your protest is analagous to:
"It is sad that my neighbors complain about torturing kittens when, for years and years, they covered up the torture of puppies."
Obviously, that's defective reasoning.
The simple way of putting this, Joe, is that two wrongs do not make a right.
Your post says that they do.
If you wanted to make a good point, you could use the pedophilia to argue tha the bishops are hypocrites. Or that their motives are suspect. Or that their judgement is poor. But you can't claim that they're wrong to defend kittens just because they didn't previously defend puppies.
