II have no problems with religion as such because humans seem to need it. They seem to need to believe in something to help them make sense of this world and their existence. Not all humans, but significant numbers.
Besides, nobody really knows if such a thing as god exists. Dogmatic atheists are no different to religious dogmatics when they insist they know the truth. Some scientists, for example, have been suggesting a so-called simulation theory where we and our world are a sophisticated simulation run by a superior civilisation. Such civilisation would be de facto our gods - creators and masters. We cannot argue that science and god are mutually exclusive as science has no evidence either way. So since nobody really knows, isn't the best way to live and let live, as AnnieK or Cherie suggest?
If people want to believe in a particular interpretation or a story that's fine. It's true that the more detailed such stories (religions) are the less probable they seem, but hey, who am I to say they're definitely not true? Not to mention that most religions are surprisingly adaptable and open to interpretation.
As long as they respect others and their beliefs, let them be. All I'd expect is for the state to remain neutral, i.e secular and tolerant so that the public sphere is not dominated by one set of beliefs.
Hope it makes sense, I had a bit to drink.
