I'm absolutely fine living under a secular government that guarantees my right to worship as I please and that does not restrict my freedoms and choices according to a singular interpretation of religion. I would not be fine even under a Jewish theocracy.You've already admitted you're fine living under atheist rules. You won't be fine with it when they fully take over.
And one more time to try and help your comprehension: Secular =/= atheist. And atheism is NOT a religion.
