If you want to see anti-white agenda, pay attention to instances of GamerGate interacting with politics...
First, Hillary campaign and pro-Hillary journalists keep lumping GG with altright and Trump, ignoringt surveys that show that most GG people are more in the Bernie camp instead.
This basically forced GG into politics, and then you got outright anti-white racism on the mix... for example one of the biggest opponents of GG is Bioware, they even made a tweet comparing trump to Reapers (mass effect antagonists, they are a species of racist robots that use mass brainwashing as basic weapon), but the same people in Bioware made blatant racist tweets, for example tweeting photo of a cup with words about white tears, making a feminist conference and writing in one of the slides that white women are against the cause and should be ignored, defending hiring decisions based on race (ie: hire everyone that ins't white) and so on.
GG also had spats with a guy that literally wrote that he wanted white people dead, twitter banned his critics instead.
Or the infamous Leslie Jones vs Milo incident, GG people dug up lots of racist tweets from Leslie, and then tried to defend Milo, and were banned instead. someone then copied Leslie tweets, made a new account, and tweeted the same tweets but changing whites for other races, and got insta banned.
GG also has lots of devs, that of course noticed GitHub controversies, including that GitHub refused to fix their official code of conduct that explicitly writes that anti-racism protections don't apply to whites.
GitHub also hired people that were already infamous on Tweeter for making explicitly anti-white racist tweets.
