I reported them for harassment with the following statement:
The purpose of this group is to review bomb any game that has gay representation. Their discussion threads talk about using other platforms to discriminate against LGBTQ+ communities and individuals to circumvent Steam’s TOS policies. This type of behavior promotes discrimination, review brigading, and toxicity. It is surprising Steam is tolerating such open homophobia on this platform.
They’re making the (correct) observation that the two things you call out as things people want to “just enjoy” are also filled to the brim with political messaging. You just don’t see it as “political” because you either explicitly, consciously agree with the political messages being conveyed, or because you’re blind to them (either because of an implicit, unconscious agreement with the messaging, or because your environment has normalized the message to the point that you don’t realize it’s political to begin with).
In other words, you say it’s a complaint about “leftist messaging being shoved into nonpolitical things,” but in reality it’s not really being shoved in your face any more than any other type of political messaging, you’re just seeing messaging you either haven’t normalized yet or disagree with, both of which make it stand out more in your brain (either due to the novelty effect, or the backfire effect, respectively).
