Stupid movies that attack Christianity and specifically Catholicism

Recently there have been movies like Religulous by Bill Maher, and another one I think called the God who wasn't there. Plus there's all kinds of books put out by atheists and stuff. But there are a lot of things they do which are rather stupid. First of all, they pick on people who have no business defending certain beliefs in the first place. People with no qualifications for example, and no experience in defending the truth. In Religulous, he interviewed one priest, who was the astronomer at the Vatican. The priest gave him a really good explanation. Not surprisingly, that's the last you heard from the priest on that movie.

Bill Maher should interview Jimmy Akin or Tim Staples or Mitch Pacwa, not Billy Bob down by the corner store. Give me a break. That's like making a movie about why bodybuilding is stupid, then interviewing a 7 year old boy and asking him to lift a 50 pound weight and when he can't say, "Well, I guess eating healthy and exercising does nothing!" Then the interviewer proceeding to lift the weight himself with some struggle and as they capture this for some time, a voiceover of the narrator comes on and says, "Hmm, that's odd, people have claimed for centuries that working out helps build muscle..." To someone not educated in apologetics (the defense of the truth), they may not see the absurdity of this claim.

I've never seen these atheists ever interviewing someone their own size, as the priest from wordonfire.org says. They always pick on the wrong people. Another example of the stupidity of this approach is to ask a random person on the street to calculate the gravitational pull of a planet given its size and composition, and any other necessary information. Then when he is unable to calculate this to declare "Well, I guess gravity doesn't really exist!" By the way, the victim of his silly scheme would not have access to any reference material and would have no time to prepare.

One movie where I did see someone picking on others his own size was "Expelled: No Intelligence Allowed" by Ben Stein. He didn't go to random people at the corner store or primary school teachers and ask them about the origins of the universe and stuff like that, he went to Richard Dawkins, who wrote some of the most read books among atheists. Richard Dawkins ended up looking pretty dumb. He couldn't answer anything he was asked. This was a fair battle, and it was won decisively by Ben Stein.

Truth always wins. Lies must slither around and use cunning tactics. It's like these videos I've seen on youtube with someone defending the Catholic position and someone else attacking it. Usually the Catholic position is heavily edited. For example, Mitch Pacwa was having a debate with an anti-Catholic man. First, the anti-Catholic would say something, and Fr. Pacwa would have a chance to respond. But on the third time the anti-Catholic spoke, Fr. Pacwa's response was not even shown and the credits came up.

My question is this: why use deceptive tactics to promote lies? Why not learn and teach the truth?
