Why should anyone convert anyone, or anything for that matter? Most the problems in the world are from people not being content to keep their own personal beliefs to themselves. Why inflict anymore damage by inflicting anymore religious thought and opinions on people, or dolphins, when we, and them, can think for our own damn selves? The world would be a much nicer place if everyone could come to terms with the fact that not everyone is going to have the same ideas and concepts of deity and, therefore, everyone should just worry about their own relationship with whatever deity that may be.
