I can't add much to the discussion, since I'm biased against xianity, and Catholicism in particular. While I strongly disagree with the religion the Pope belongs to, I feel he has as much right to discuss his views/beliefs as anybody else. Is he a jerk?
I guess for me personally I'm not that fond of any kind of salesman. I don't like telemarketers calling me, I don't like signs and ads and billboards and commercials bombarding me each and every day, I don't like people trying to push me to get the latest model of their product, or purchase the extended warranty. If I WANT help or advice, I'll ask for it, and be appreciative of it. But when help or advice is foisted on me unasked for, I tend to resent it and think ill of the "helper".
I see religion, particularly xianity, as being a sales religion. People here are always trying to sell their faith. "Sign up now and get a free jacuzzi in the afterlife !" I feel constantly bombarded by xian propaganda to buy in to their religion, from door-to-door salesmen, to tv networks and radio ads, to flyers on my car windshield, to Chick tracks in phone booths, to street-corner proselytizers, to politicians vying to out-god each other. This stems in large part I feel from the order to xians to spread the Word.
It would be nice if the world let each other alone, but pushing people to follow you and think as you do is sadly an unfortunate part of reality. If xians are going to push me to swallow their blue pill, and nobody calls them jerks on it, then I have no problem with others pushing back, advising to take the red pill.
As an aside, I like this line of yours:
I'd just like to add that dumber people often find clever people arrogant.
