Um, how would you do that? Do they sell big bags of religion eradicator next to the grub killer at garden stores?
OK, I'm putting up the sarcasm now.
Why are some people so cranked up about what other people believe? I feel like if it isn't harming me then it isn't my business. For instance, I wouldn't want to be Mormon, but I don't really care if Mitt Romney is. Why would I care? I have enough to do just keeping my socks clean and fresh.
If you want to have personal freedom, you have to learn tolerance. If you find certain beliefs abhorrent, you have to find a way to detach from the fact that some people choose them. When tolerance isn't possible, you can always cultivate detachment. But most of the time, tolerance IS possible and not that hard, really.
I used to work at a place that employed many right wing Christians, and I am very obviously not one. Sometimes people would pitch me their take on salvation and what not and I'd just say no thanks. It doesn't have to be a big battle. A polite no works in most cases even if you have to repeat it several times. It's the politeness that is key. Politeness AND no thanks. It's only on the internet that people are so pushy and rude. I rarely experience that in person.
I can also tell you that I've learned a lot about people by listening to what they believe and why, and even though it might not be for me I sometimes end up having more respect for them once I can be still enough to listen and not so anxious to argue.
Religion is vital to many people. As long as no one is getting burned at the stake, I think we have to let people make their own choices.
