All you have to do is write something short and nice that is not your own belief, faith, or other. For example, if you're a Christian, you can say something nice about atheism. If you're an atheist or agnostic, you can say something nice about Christianity, Islam, Buddhism, etc. You're even welcome to say something nice about Satanism, Wicca, and Pastafarianism. Although it must be about a current religion or belief system today, so no ancient religions such as Mayan, Greek, or Egyptian to name a few. No fictional religions such as the Esoteric Order of Dagon and unitology; although Jedi Knight is the one exception since there is a religion in Australia that identifies as Jedi. No cults either. When you are talking about a belief system don't single out to one specific denomination. For example: Christianity has Protestants, Catholics, Lutherans, etc. Say something about Christianity as a whole rather than a single group. The point of this challenge is to acknowledge the other. While we all may not agree with on the same thing, that does not mean we should divide ourselves any further, or cause any more fights among us. All you have to do pick a religion or belief system that isn't your own and say something nice about it. Can't be that hard to say something nice, can it?
