The only things I say about religion are:
1) If you want to believe in a higher being, keep it to your church and home, I don't want to hear about your religion and how great it is. If God wants me to be enlightened, he'll do it himself. For instance, for Easter we had two people from a church come in and basically tell us to read the Easter story because it will make us better people. I'm not even part of a Christian school, so I don't know what gave them the right to come and say what will/won't improve my life.
2) Have a mind of your own. By this, I mean don't blindly follow the word of some higher being you have no evidence of. Use their teachings as a way to base your life off of. Biggest example is the religious that don't like homosexuality, only because some old guy thousands of years ago said it. Make your own opinion, do the research into homosexuality and then you can say what you think about it.
3) Don't indoctrinate kids. Babies are far more susceptible to ideas than children, ideas that can stay with them for their whole life. My opinion is that kids should be told about religion at the point that they are able to talk well and properly think for themselves, if you get what I mean.
I won't be answering to any replies of challenge or comment, as I have been known to get into quite heated debates on this subject, and I would like to try and avoid that, for everyone's sake.
