Stop being condescending. The truth will always prevail. Start using simple facts and let them decide for themselves. This is is only way. Those who cannot see, will never see. Move on.

I think I saw it somewhere not to talk about it just to be about it and make others ask themselves the question, "what in the world have they got and how do I get it."
I have got to be honest though, It is the best thing that I have ever known and not sharing feels like an absolute evil thing to do. Any one can have it so why try to keep it to myself?
