You get attention with a red flag only from a bull. When we meet people who ask us about our faith, we have a responsibility to refrain from telling them every last little detail. But the cover is what will cause them to open it up and read. That's where standards are so important. And not just standards of speech.
Words are only one form of communication.
How we dress, the manner in which we present ourselves and the way we treat others all play very important parts in our ability to communicate. I go to work in a shirt and tie not because I enjoy the trouble it takes each morning, but because it is a standard that conveys that I am a professional. Similarly, when others are in a position to examine our religion, they will judge it on the basis of what standards we have set for ourselves. If we are to be interviewed on TV, coming in full ritual robes and jewelry will not set a tone of good communication. All it will do is brand us and our religion as strange, rebellious, and out of sync with our world.
