Dangerous People

How do I know if someone is dangerous? If anyone that I meet anywhere on Earth tells me that if I don't believe what they do that something bad will happen to me. These are the most dangerous people on earth.

How do I know if someone is safe? I know someone is safe if they believe in "Live and let Live" and understand that there are an infinite amount of points of view in this constantly expanding universe we live in.

So, someone who is safe to be around understands we are both human beings and is tolerant like me of others with other points of view. It doesn't mean that they believe the same as I do. It just means that they will allow me to live my own life in peace.
