I doubt it would frighten a young child. As a matter of fact, the only way to wipe out intolerance is if children are exposed to differing lifestyles and opinions from an early age. Why would it frighten them?? Perhaps because an adult in their life planted the pre-conceived notion that those people are bad into their small brains??

Freedom of religion is just that. It means that people are free to practice their religion of choice, or no religion at all, without the fear of discrimination. There are many Hasidic Jews where I live, and they are dressed quite differently from the rest of the community. Should we ask them to shave their beards and curls, and remove their hats because they look different or "scary"?

Tolerance is the answer, not asking someone to violate their beliefs to make someone else more comfortable.
