Jim,
You're looking for a response from me, but I'm not sure what to say.
As for creating videos or whatever, there are many tools online as well as instructional material. Create a youtube channel or start a blog. I hope you are successful in changing the world.
Arguing with the "crazies" is not a complete waste of time. Sure, there are many people who you won't convince. Do it in front of an audience. There are many fence-sitters out there who will be nudged in the right direction by a good debate. Also, you can use these debates as a way of educating yourself. I certainly understand if these sorts of debates are not your cup of tea. They're not for everyone.
There is certainly a lot of non-thinking that goes on with religion. I certainly feel that my time as an atheist is well spent in speaking out against religious belief and all of the negative baggage that entails.
