But the quoted extract from The Universal Declaration of Human Rights Article 18 : "Everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief..." seems to me to be defective, in that it refers to a "religion or belief". A bloody-minded person or government could argue that atheism is not a belief, but an absence of belief, and therefore not covered by the Declaration.
I agree, Eloethan, but atheism means without or no god, which to e.g. the Indonesian government can be interpreted to mean a belief in nothing, i.e. a non-belief. I just feel that in the light of experience the drafting could be improved. Mind you, the drafting committee would be an interesting gathering!
