Nothing will change because half the people are using a metric that the other half simply don't believe in. It's not just that they don't agree with them, they just don't believe in the metric at all.
It's like some guy coming to my house and telling me that his religion means I have to paint half my body green. No matter how much he believes this to true, unless I share his religious beliefs, he just sounds ridiculous to me. And if he believes his religion to be true, no amount of argument from me will ever override the position taken by his "god".
I'm never going to win an argument against your imaginary friend.
(And I say this as a practicing Christian who has enough sense to realize that my religion really only governs what I do, not what my neighbor does.)
