I am observing a very similar sentiment to Sinophobia, now regarding Russia. Reddit's audience is primarily 80% USA + West EU, and the rest 20% also includes a lot of East Europe and other countries, leaving for 5-10% anti-hatred people. On the other hand, Western world makes up for a mere 12% of the world's population.
This speaks volumes about how majoritarianism is flipped on the internet by Western world to suit their narratives and loudmouth whatever they want dominating in virtual space. And since moderators are also from said Western countries, the biases are completely intentional and systematic.
For all the "human rights" and "no censorship" nonsense these Western countries spout with the assumption of having high horse on moral grounds, they lie a lot systematically.
Just an observation.
maybe now's a good time to share that Reddit has always had rampant Russophobia. Back in 2016 when the Enough Trump Spam subreddit was made, they added "no xenophobia" to their rules. but every other post was xenophobic towards either Russia, China, or the DPRK. Hell, I got like a thousand downvotes on a comment where I corrected the OP on the reach of DPRK's missiles (it was one of those "oh no, the north koreans are going to nuke us next week" posts), and nearly all of the thousands of comments were calling me a Russian bot, or using slurs to insult me.
Russophobia was a big part of the Democrat's strategy against Trump in that election, claiming that Russia helped Trump win and whatnot. Russophobia is at this point, perhaps, the oldest propagandist tool used by the American state. Ever since the revolution in Russia, and honestly even before it, they scaremongered supporters into supporting whatever it was the politicians or the media wanted them to support, using Russia, the Soviet Union, or Communism (which was tied to the Soviets for them) as the leverage. Black people want rights? can't do that, that's communism, and look at what's going on in the evil USSR. Workers want rights? can't do that, the evil USSR. so on, so forth. It's very disheartening that they still use this tactic today, but it's even more disheartening that in the information age, where anyone can simply look the information up and disprove the propaganda, people still eat the tactic up like day-old fries.
