Of course it's dry and common knowledge. Sometimes people need to return to the basics, because it's amazing what we can convince ourselves when we add complicated "exceptions." Sometimes we just can't see the forest for the trees (or do we fail to see the forest 'cause we're looking only at the individual trees?), 'cause we just create this massively complicated system. But, here's the thing, to even
attempt to be politically neutral, there's only 2 possible methods.
1. You can ignore the bits that are perceived to be currently political.
2. You can say that everything is welcome.
GOG obviously takes to 1, because that's the corporate stance of the day. The issue is, even the social media companies have realized at this point that this is absolutely untenable, for the reaons i've described above. Say that "annoying orange" became a meme to refer to a particular president? Are you going to retroactively delete all posts and possibly issue bans for "annoying orange for president" if there was a skit back in 2008? Ok, maybe not bans, but then how do you deal with the userbase who posted those comments? What about the "remember this?" stuff on facebook, or, say gog forums, a necropost? Say you say it's ok, don't delete it, and allow even contemporary posts as long as they reference the old ones. Now you're half-assing method 2, and making annoying orange fans have exclusive immunity.
Method 2, creates fighting and argumentation. However, we can also see that this wasn't always an issue. Prior to the American Civil War, people were able to disagree on huge fundamental issues, without hating each other, just getting sligthly unfriendly on certain topics. Sure, there'd be a brawl at a pub, but, well, how's that any different from now? I'm sure you'll find some famous cases of dueling, but, well, we rightfully see that as an improper way of handling disagreements, and most times we know of seem to be more about power by other means than by politics. Some people i can talk to, disagree with strongly, and they don't want to kill me afterwards. Some people now i can have a minor disagreement with, and they want to kill me (this is rare, but it happens). It would appear that policy 1 is at fault: we become increasingly polar and are increasingly fragile to criticism and disagreement, because our skills of debate and disagreement are not honed, we come to see these things as existential threats (microaggressions).
Now, by all means, we can talk about what is historically been done on gog, but then we do have to bring up which system is smarter and healthier, and if it's the latter, why is "doing what we always do" more important than change? And, well, this is weird coming from a conservative, but, then again, history shows we've went from system 2 to system 1, so maybe i'm just ultra-conservative. Either way, you just aren't going to truly avoid politics in games: it's going to happen inevitably. The question is whether or not you let politics control the games.
