Believe everyone who asserts a belief in beings absent any empirical evidence
may be mentally ill. As indications go, it'd be a big one.
Beliefs are taught and learned so not a default anything.
England sent its religious nuts to America and its criminals to Australia. Australia got the better deal.
Well anyone is entitled to their own opinion even Sigmund Freud and other famous genius. There is no scientific basis that God exist but science cannot prove things that belief can.
It's a slippery slope and is actually non arguable in my opinion.
If to believe is a mental disorder then everyone is mentally disabled. Even atheist for they still believe in something which is the non-existent of God, that's their religion.
So everyone is mental. That make sense I think. Anyway, I said it before and I'll say it again. Believe what you want everybody has that right
but please respect the belief of others as well.
