It's also a real weak confederation he's forming.

The "we the theists (or I guess non-nihilists?) all agree that..." falls apart once you start finishing the thought because they don't agree on much outside of negative partisanship towards certain outgroups before splintering back into fighting about dogma. Buddhists and Baptists both think life has meaning, and that's a statement with low utility.
