I agree with you in spirit, except I think it makes more sense to think about religion as the totality of a person's beliefs. In other words, everyone has a religion, and there are as many religions as there are people.

And with that definition in mind, it's not religion per se that needs to be trashed, but rather, any claims that aren't backed by publicly, democratically observable evidence.

And I don't think such claims should be banned per se, because that opens a whole can of worms by which whoever is in power gets to decide what counts as 'evidence' for a claim. And I don't like the idea of the state dictating what we can say or not.

But what I would like, is a culture shift. Currently, a lot of people think that personally held beliefs are sacronsant, and that it's disrespectful to even question someone else's private beliefs. But I think that we should instead think of it as our responsibility to give and receive critical feedback on everyone's beliefs - with the ultimate goal of encouraging everyone to rid themselves of beliefs that aren't supported by evidence.
