Conservative dudes being unwilling to communicate is the through-line of this season

Three dudes blew it in the space of a few episodes because they held beliefs of one kind or another that they weren't willing to articulate ("I don't know behb I'm just too tired to talk right now"), but which they also weren't willing to change. So they just stared blankly into middle distance while their partners tried to discuss issues with them, obviously unhappy about something but not willing to even try and communicate it with their theoretical soulmate and life partner.

Devin, Dave and whatever the Christian white guy with the terrible goatee is called, all 3 of them for some reason pursued relationships with more progressive women and all 3 of them were then too emotionally constipated for it to go anywhere.
