Although I was raised without religion, I was also not raised to be against it. My parents let me find my own way based on my interactions with the world and the people I met in it. This said, my dad is very much an atheist. He and I love to watch Richard Dawkins videos together, read science books, and watch documentaries like Friends of God and Jesus Camp and just shake our always questioning heads.
Recently, something interesting has happened within my secular household. My sister just entered middle school this year, and is somewhat of a social butterfly. She got several invitations to a youth group that "everyone" goes to, and finally they created an event exciting enough to catch her. She now goes to youth group for the occasional scavenger hunt or hunger strike or whatever they're doing that is absorbing enough to even entangle a non-Christian child.
My parents still have a hard time letting her go, and I have heard them talk about it in hushed voices in the kitchen. What I find amusing is that I feel like my parents would almost prefer my sister be shooting up heroin than going to youth group. A definite hyperbole, but nonetheless effective in illustrating their level of distress. I just feel very strange living in a house like this. On the other hand, I find youth groups to be very disturbing myself. Almost everyone I know went to one when they were younger, whether they are religious or not. I just get so angry thinking about the brainwashing and subliminal activities that are taking place. The use of fun and games in order to harvest lifetime believers is far from respectable, in my opinion. If I ever have children someday, I hope to raise them in a similar way to how my parents raised me. I don't want to force beliefs, or even a lack of beliefs, down their throat. I just want them to question, and never stop.
