It doesn't imply that at all. It isn't the wisest comment but all it says is that there's some irony that a company that KNOWINGLY gave a huge signalboost to a hive of pedo-Nazis is getting a reward in German gameshow (basically, "funny how the gamer community doesn't give a fuck"), a country that cracks down on Nazis/Nazi propaganda fairly hard. That doesn't imply anything about everyone at THQ being nazi supporters or that the poster thinks all Germans are Nazis (which is what you said in your first post).
And, again, "gamers" aren't some oppressed minority. "Gamers are trash" isn't some harmful generalization, it speaks volumes of the current state of the hobby where women, POC, gay & transgender people & such have to abandon it (or at least not participate as freely & openly as they'd like) because they face so much toxicity & harassment from (mostly male) gamers.
That's the way I interpreted his post, so I apologise to the poster if I misinterpreted what he said, it read like he was implying that Germans = Nazis and it seems that many other posters interpreted it that way as well, along with the mod team.
Even if that wasn't the intention of the poster, like you say yourself, it wasn't the wisest choice of wording but again, if I am wrong about this I apologise to the poster with complete sincerity.
"Gamers" when referring to people who identify themselves as such to align with a hateful ideology, I agree.
But "gamers" as a general term to describe people who enjoy the hobby of playing videogames most certainly does include oppressed minorities, POC, women, gay and transgender people all play videogames, so when a term like "gamers are trash" is used, for people who understand the context (you talking about an ideological hate group) it's acceptable but for most people outside of that it just seems like a harmful generalisation because it's effectively putting all those other groups under the same umbrella, for most people, gamer isn't a word associated with a hate group, it's just a descriptor that tells someone they enjoy playing videogames, for example, my neighbour is a casual videogame player, he plays Fifa a few times a month, when I first met him he asked me if I was a gamer, I don't think he was asking me if I was a member of a bigoted group of inviduals who have taken the word in a hateful ideological sense.
I do completely understand your perspective though, don't think I am dismissing it because I am not, there is massive problems with toxic behaviour, especially within online gaming communities and it does drive people away, especially the groups you have mentioned as most toxicity involves slurs regarding these groups and it's definitely something that needs huge improvement, just yesterday I got told to "get cancer" because I killed someone on counterstrike, so I know it exists but I also realise that the majority of people don't behave like this.
