Gaming culture is more toxic. It's because of GamerGate.
GamerGate was an online harassment campaign, conspiracy theory, and lie that the entire gaming industry was trying to ruin games by pandering to "SJWs". Women, queer people, minorities, and the disabled were being shoehorned into games as "forced diversity" in order to brainwash gamers into leftest politics. Worst of all, white cis hetero men were being forced out of the gaming space that always belonged to them.
Obviously, the solution to this dastardly plot was to dox, harass, and swat people declared, on the flimsiest evidence, to be behind this plot. Anyway, this was very successful and the tactics, bigotry, and mentality has so infiltrated online gaming spaces, most of the people being toxic today learned that behavior second or third hand from those who actually participated in Gamergate.
IDK if this was coordinated, or spontaneous, but the "alt-right" was very active a this time trying to meme Trump into the white house. Even skeptic spaces that are left wing about almost everything else became cesspits of Islamophobia.
