The point is anything goes and so anything goes--we can go round and round about paths and case studies and freedoms and all be 100% right.
But I agree with Lapis. Anything that puts a firm limit ON ITSELF such as a claim that it is the only one true way, etc, therefore puts a limit on my acceptance of it. I don't stop anyone else from doing what they want to do, but spiritual exclusion or apathy to it I will not indulge others in, and that is as much my right as a individual as it is others to practice what I do not agree with. ;)
