I'm pretty open minded when it comes to different forms of religion. More open minded than you realize. But I wonder about the spiritual well being of atheists. And there are a lot of atheists on HB.
I understand that your "wondering" comes from an angle of concern for well-being and not some attacking accusational thing, and I appreciate that. We may disagree, but I think your heart's in the right place.
A distinction can be made between spiritualism and religious. NUance, it sounds like you and I choose to express our spirituality through our religious beliefs; however, religion is not the only outlet for one's spirituality.
