Regarding sexism and the games industry, I'd like to mention the Petrie multiplier: "if the percentage of men and women in the room who make questionable remarks to the other sex is equal, then the average number of sexist remarks experienced by members of one party scales by the square of the proportion of the offending party to the other". This means that, the less women you have making games, the harder it is for women there.
(This can and should be generalised towards non-binary and trans people, too. It gets even worse for them, through the same mechanic.)
One wonders: Is it video games or the Internet itself that needs to be fixed?
Neither - it's society itself.
