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.
Diversity Equity Inclusion. Some businesses have some people to try to make sure their hiring practices aren't discriminatory, and that's referred to as DEI.
But racists are against all of those things so to them DEI is a bad thing. And as these things go, DEI has become a codeword they use to express anger at anyone non-white having a job or represented in any kind of media. Like most dog whistles they pretend that they're cleverly avoiding being overtly racist but it doesn't fool anyone.
