If you sit at home, stare at a screen filled with horrible stories all day, find no fun in anything but only things that offend you or even look for offensive stuff in 10 year old comedy skits... you eventually get depressed or it just fuels your depression.
Sure, shit on 4chan/Reddit all you want, but I would say the absurdist/nihilistic approach works better than soaking in your own self pity.
4chan and Reddit are also much more random, compared to say looking up 'OH GOD THIS IS OFFENSIVE' videos on YouTube. As it will just recommend you more of such videos.
Reddit also varies from board to board. If you don't like a community you can simply chat up people with a different interest.
REE works more like the YouTube algorithm in this regard.
"WOW this game is shit

"
"Yes this game is also shit

"
"Wow, this movie is offensive

"
"Look at this other thing I found that is offensive!

"
"This developer is a GamerGate Nazi

"
"Every other developer is also Nazi

"
Look no further than the Smash Bros. thread for a good example of this.
It starts out with:
"Donkey Kong is being used intentionally to fill in for POC characters!!

"
And now the accepted point of view (because if you don't agree with this, they ban you) is:
"Sakurai is knowingly advocating racism in his games since he started making them and will never apologize for it!"
Which is fucking bullshit but hey you can't actually ENJOY anything when the world is ran over by Nazi's hiding in every corner!
