If God really exists and cares for me, he won't worry about what I believe today.
Now if you believe your God is this caring spirit, you don't need to tell us we are wrong. If you believe he is a judgemental authoritarian, then you should be letting the naiveists among us be cleansed with his judgement. Either way you should be careful, some of us get rather annoyed and vengeful when told what we should believe.
