No, I have a problem with being a jerk. We can defend and still be charitable. There is no call for rudeness. If you want to be treated properly, you should extend the same to others.
Look, many people want others to respect Catholics. Then, they turn around and call Protestants dumb, illogical, and whatever else. How can you justify this? It is the SAME as homosexuals making fun of us because we won’t allow them free reign in the Church to sin as they see fit.
Just because I will not tell TU that he is going to hell for being a Lutheran does not make me a bad Catholic. Just because I will not tell Reformed to shut the hell up with his reformed theology does not make me a bad Catholic. Just because I will not call Edwin an episcopalian liberal secular humanist does not make me a bad Catholic.
We are called to preach the truth with LOVE. When someone is mean, cold hearted, harsh, or just plain rude, they destroy the message that they profess. Bashing people upside the head does not create Christians. If you fight fire with fire, all you are left with is ashes.
