I agree, these items however are not what is being discussed in this topic. Most of these items are illegal and or dangerous in their own right (by the way, kids will see items like condoms all the time when mom and dad takes them to the store). A crucifix, Star of David, Buddah, or a Cow (a highly regarded religious symbol in some faiths) are not going to hurt anyone, even children. If your not Christian and your child see a cross (which I'm sure they have seen hundreds of times before) and they ask what it is, all a parent need say is that "It is a symbol that represents someone else's ideas about life." No harm is done.
The items you list above are VERY different, harm will be done. The religious symbols being discussed in the forum hurt no one, they may make some people feel uncomfortable, but no harm is done. I find it interesting how so many people come out and scream about a cross or a Star of David, but then go home and let their kids watch rated R movies full of rape, murder, violence, etc. and hardly even say a thing. I believe this is much more damaging to a child than any cross you will find in a cache.
So if we carry some peoples comments out to their ultimate conclusion, we need to come up with a band list that includes EVERY religious symbol in the entire world to be completely fair and not accidentally offend someone. By the way this would include all kinds of things, like Cows, Roosters, Crows, in addition to what we always think about as religious symbols. I'm sure someone out their would be upset to find a sacrilegious depiction of a cow on a GeoCoin that may for instance be honoring farmers.
Use common sense people, if it is dangerous or illegal, then no-duh, it doesn't belong in a cache. People preach tolerance, tolerance is the ACCEPTANCE of other's beliefs and ideas and that they can express them (even if you don't agree), telling them that the have to hide it in the closest because it might offend someone is by definition in-tolerance. A lot of people died giving us our right of free speech, freedom of expression and freedom of religion, and the right to not agree and state that you don't agree. Any Christian worth his salt will tell you that Christianity can not be forced on someone, those that try to are in the wrong, accepting Jesus has to be a willing non coursed decision made individually.
