I have got better at accepting that no matter how many times you prove something, and no matter how many times you provide practical examples of what it is you are looking to prove, certain individuals will not be moved.
They will not change their position, even in the fact of incontrovertible and overwhelming evidence.
This is fine, I accept this now.
There was a time when I could not accept it or understand, and I would have another go at explaining.
Many people have, for their own particular reasons, the need to believe what they believe.
Even if the evidence and data prove quite the opposite.
