Guess Phil will now be a victim of... *checks notes* alt-right indoctrination.
FWIW steam does have a bad right wing recruiting problem. Some nazi gaming groups etc that have stuck around for too long.
That said, I think it's hard to paint it all with one brush because for all the toxicity I see in parts of the steam forums, theres often a lot of pushback against that sort of shitty rhetoric from the same communities. It really depends heavily on a game by game basis as well. As a result it's hard to assess exactly how widespread it is.
My only anecdotal perspective is I've used steam for 8 years or so actively, and have only sometimes brushed up against bigotry and the like, and usually it was removed following reports of community pushback. But I also don't play a lot of "Historical Simulator" games where I hear the problem is a lot worse.
Edit: this thread goes into some details and there are some external studies linked.
Steam has a right-wing extremism/racism problem on their discussion forums that needs to be addressed.
Specifically under the DEATHLOOP discussion threads I'm seeing tons of hate against people of color. People boycotting the game because it is "WOKE" and has a black protagonist. I...cannot believe that nobody at valve has tried to combat against this...
