Garry's Mod has typically been an open community, more so than most, since the game itself is functionally a giant sandbox for players to fuck around in. You would think, that since any idiot can create a server for it, and the bulk of the game's userbase consists of 8-to-16-year-olds farting around in a controlled environment periodically backed with older people using it for testing, design work, or animation, that it would be mostly immune to the ravages of the outside world, but Autism being what it is,
Garry's Mod has seen an increasing infestation. A lot of Facepunch Studios' staff are pretty hard-left, and while they're far from the worst community about it, a general synopsis of their forums is "trying to be SA." While much of facepunch's staff are pretty infamously bad, there are few more well-known than
Maxofs2D, who is/was a raging SJW and we have a thread on, and who constantly spammed DMCA requests and was sort of a far-left Mikemikev analogue according to the ED crowd.
But the biggest issue comes from none other than than Garry Newman himself. See, back in April of 2016, Garry Newman made it so that race and gender were randomized on character generation for Rust, rather than giving players the ability to customize, which is what most wanted. You now have no choice whatsoever about who or what your avatar is, and Newman
sung to the heavens from a column in The Guardian about how this totally wasn't done for identity politics reasons before basically undermining that in his own article:
Garry said:
It’s maybe understandable why some male gamers wouldn’t want to play as women. They’re just not used to being forced to. You could probably count on your fingers the number of major, big-budget games where you have no choice but to play as a woman, never mind having no choice but to play as a black woman. Female gamers are obviously more forgiving – they’ve been playing games as men for most of their lives.
Worth noting, in the same article, he claimed it would have taken "six months" to put in the ability to select your race and sex, something that not even the most tech-illiterate moron believed. Of course, Garry is also the same prick who
was pretty openly in favor of the nexus mods system because of the potential money it would bring in, so make of that what you will.
