It is not about taking sides, it just does feel wrong to throw your politics into a Game Jam. (And I am nice saying ‘your’, because I guess that most people’s politics are merely the politics of the media they listen to. Crowds have no critical thinking of their own.)
(For the record, before I get the ‘Putin apologist’ label — which would not even be an insult per se, since you would then have to discuss who is right with the person in private —, I oppose both the NATO block and the ‘Russian block’; not a fan of geopolitical dialectics nor manipulative dialectics in general.)
