The main issue is that they aggressively defend countries like Russia, China, and North Korea. The simplified reason for this is that they are communist countries that, they claim, are oppressed by sanctions and misrepresented by the west.
They also really like whataboutisms.
It's sad because most former redditors might actually agree with a lot of their leftist beliefs, but hexbear users seem to be very stuck on supporting and making excuses for fascist regimes.
I now brace myself for a flood of downvotes and replies. I beg of you, please keep the whataboutamerica replies to a minimum. I already know and agree that america does bad things too.
The real thing wrong with Hexbear is that their favorite sports are brigading, trolling, and namecalling. As you'd expect from that list they are also pro-authoritarian.
