There's a different read of this by people such as Stirner. As he pointed out, people only ever abandoned the divine subject but left the divine predicates intact, making the tyranny even worse because now even the unbeliever can't escape. They never abolished religion but simply changed the masters. I think it's worth quoting the text because it has always to me explained why so little has changed in this regard:
"But, properly speaking, only the god is changed - the deus; love has remained: there love to the superhuman God, here love to the human God, to homo as Deus. Therefore man is to me - sacred. And every thing 'truly human' is to me - sacred! 'Marriage is sacred of itself.
And so it is with all moral relations. Friendship is and must be sacred for you, and property, and marriage, and the good of every man, but sacred in and of itself. Haven't we the priest again there? Who is his God? Man with a capital M! What is the divine? The human! Then the predicate has indeed only been changed into the subject, and, instead of the sentence 'God is love', they say 'love is divine'; instead of 'God has become man', 'man has become God', etc. It is nothing more or less than a new - religion."
