For Hexbear at least, I can see two of the reasons: 1) they support the idea of a polarized world where other powers are able to compete on equal terms with America. 2) They must present a united front to those outside, the “enemy”, because doing otherwise would provide them ammunition and weaken their own team. For having lurked long enough on their turf, I’ve seen more nuanced takes on Russia and China that recognize their wrongdoings. Even by the same users who’ll be total shills in a World News comment section.
