We know what we know and we don't know what we don

We know what we know and we don't know what we don't know. Don't dismiss apposing view points out of hand, if and only if they are presented logically, with the same doubts expressed as those you don't agree with. But civilly put, all OPINIONS are valid. We can discuss without flinging poo. I am saying this to our group in general and this is not intended toward any individual or group.
