That's all very well spoken. Science (the 'hard sciences') do not have the answers to everything. The scientific method is a tool (like a shovel or pick axe) that we use to investigate our surroundings. There are massive mysteries that exist inside this reality. Science, religion, philosophy only scratch the surface of this grand mystery that we all experience.

I fail to see how objectivity and religion/spirituality are not in conflict when the latter are based on one's own projections onto the unknown? Sure, this isn't directly affecting me, but the moment religious or spiritual people take decisions or actions that affect other people, this can involve me. Think of abortion or other ethical debates. Or even morality, which is a huge pile of shit all thought up by religious people from their own projections. This is affecting me in my daily life, because I get confronted by a sexist, transphobic, homophobic worldview all stemming in huge parts from religious teachings. Even if the people marginalizing me aren't religious, they still got their morals from our religion-indoctrinated society. This has been a huge and often deadly undertaking of so many people to get rid of these morals and to don't judge others.

We all project stuff onto others or onto the unknown. I just want us to be honest about it and that we try to be transparent about it. I'm totally fine if a person says that they believe in something superstitious, god, etc as long as they are aware that this is a product of their own mind and that they don't value others differently because of it. I think in the end it boils down to values (which is the basis of morals I guess). If your values are informed by your own religious/spiritual belief, then this seems problematic to me because it will affect people negatively. But as long as a person can separate their own belief from their values, I'm fine with this.
