So if you already have a totalitarian state (see Shah Iran) bringing in religion will make it worse, not better (the current mullah Iran).
Sadly, I don't see any good perspectives. In rich countries, the main voting power belongs to people of considerable age. And they don't use much freedoms therefore freedom is not a selling point for politicians; medical care and pensions are.
And in poorer countries you can always band together enough Red Guards to establish a totalitarian theocraty if you don't have one already.
Going against religion won't do any good to protect free speech or any other human right. You'll only gather more enemies.
Why does religion go against us, but we should not go against it? They take pride in hurting whatever I consider worthy.
I think we should not be tolerant to people who violate basic human rights. They either behave or we should find a way to catapult them away.
Because I'm advocating against that.
