I think you might be taking this internet thing a little too seriously. We all have misunderstandings about stuff but it’s not good to stubbornly insist that you know what you’re talking about despite clearly never having actually looked in to the material. That’s the extent of my tearing in. But you are right in that I should do better about actually saying things of substance instead of trying to be snide all the time.
40k is, in part, parody to make fun of fascists. That’s why it’s so absurdly over the top. The fact that fascists like it says more about them than the setting.
Did the opposite for me. I was so tired of seeing stuff about it back on Reddit that I filtered it out. I think it made me less likely to buy the game due to exhaustion. People just wouldn’t shut the fuck up about it and nothing else could get through.
