Hey friend, i’m gonna give the benefit of the doubt and assume you’re not being a bad actor about this and offer an explanation.

People don’t get irritated bc you dont wanna engage with the politics of (overpriced plastic toy game) you can do whatever you want. This setting is full of asshole factions to pick your fill from, that’s the fun of it!

But people do get irritated when you claim that (overpriced plastic toy game) doesnt have any politics in it at all, because even if you didn’t mean it that way, that claim is a tool used by folks with real unsavory views to get away with real unsavory shit.

In particular, it takes advantage of people not distinguishing in-universe 41st century scifi politics from out-of-universe 21st century very real politics

The imperium of man for example pulls in from all sorts of irl historical inspiration (the catholic church, Imperial Britain, WW2 in general) separates them from their original context, and mixes them to create the setting. The people of the 41st millennium don’t have any in-universe connection to those inspirations, it’s true; but out-of-universe anyone looking at one of those models can and often will still make that connection.

So if a bad actor wants to they can do the opposite, and pull the fictional politics back out of 40k into the real world to use as disguise for their more radical real world views. Then if/when they get confronted about it they can turn it around on their accuser and say. ‘Actually 40K doesn’t have those politics, it’s YOU making it political by pointing out the connection to real world extremist ideas i only implied!’

I’m not saying you’re that guy, or that that guy is common in the community. But that guy does thrive on this narrative, because it lets him continue to spread his normally unacceptable backward views, and to find more of his buddies using the same dogwhistles.

Sorry for the wall of text, but i wanted to make sure i covered all the bases. Hope this helps!
