Here's where I think we differ: a lot of people in secular western culture are intensely put off by all the religious stuff that comes with Buddhism. The metaphysics and reincarnation stuff is, in my view, a reflection of the culture that Siddhartha Gautama grew up in and taught in, rather than a necessary part of eliminating suffering. I think that retelling these lessons in a way that's accessible to modern audiences is important. Some people simply will not accept something taught in the form of ancient mysticism. Should those people be denied insight just because they didn't grow up in India during the Iron Age?
I get that Ingram is polarizing. I'll add a link to Mahasi Sayadaw as well, but I just don't think he explains things in a way that's as clear to someone with my cultural background.
