karnak1: Speaking for myself I think the issue is that nowadays too many people (including game devs + publishers) worry too much about what the "vox populi" and the media have to say.
I know this all too well since - throughout most of my life - I've been called a "communist" by the rightists or a "fascist" by the leftists. Still, my opinions are my own. If one doesn't like them, they can go screw themselves. In the same way, I think all the people have the right to have their own opinions.
If the devs of this game are radical socialists, then good for them. I only care if the game is good or bad. If it's good, then I want to play it.
A similar situation happened when GOG wanted to sell
Grimoire here and, regardless of the quality of the game, there were people complaining that it had no place on GOG because it was supposedly made by an alt-right fanatic.
Should we also ban every book and film made by soviet authors or supporters of fascist states? - But I digress...
My opinion: as long as the author is not a sociopathic murderer or a pedophile, if his/her work is good, I want to have the right to enjoy it.
The issue is not a game-maker's politics.
The issue I have is what the game-maker has written on the game's page -- advocating violence against a class of people.
If that level of crassness is inherent in the game, then I do believe that this game should not be on GOG. If that level of crassness is not inherent in the game, then "cleaning up" the game's page would seem all that is needed.
