As for me, I certainly recognize several of the positions he describes, so I don't think it's a complete straw man. But I also haven't observed several of the attitudes he describes.

Seems to me maybe what he's seeing is not a religion where people are required to hold two incompatible beliefs in their head, but the result of public discourse where basically rational and consistent, yet angry, people fall on different sides of an issue and their voices in concert become incoherent.

In which case, the solution is perhaps: don't get sucked into the sturm und drang based on everything you read on Reddit. Be compassionate. Pay attention to what's around you. Look for opportunities to make a difference.
