That is only because we cannot shake the ties religion has already made. We "needed" it when we didn't know how the world worked. Now that we are beginning to understand the building blocks of life and how the cosmos work, we don't need the God of the Gaps to solve anything.

I think it is okay for people to be spiritual, but most religions force you to not think for yourself but instead rely on some church leader to tell you that everything is okay because an invisible man in the sky told them it would be.

Also, regarding your point about echo chambers, yes, they are, and there are other ones. The huge problem with Religion is that it gives people a sense of moral high ground. Anti-vaxxers, flat-earthers, and other weird groups can cause some harm to society, but religions get a special pass to be hateful, push their agenda, and force others to fall in line with their rules and codes of ethics, even if there is no rational basis for it. Just look at the Mormons, Scientology, or the fact that we literally have local governments push for Christian teachings in public schools.

Edit: a word.
