Let other people do their thing so long as it doesn't affect my safety or someone else's. If whatever their doing isn't hateful, violent, or likely to cause unintentional or otherwise intentional harm, it doesn't matter what they are doing. I don't care about someone's orientation because it doesn't concern me. I don't care about religion because it's none of my business, etc. Basically, let bygones be bygones; live and let live.

What's yours?
