Yes, exactly! Plus, things are supposed to improve, not stay the exact same. Their evidence is completely bullshit if you think about it.
In 2020, there were slurs and insults, as you said, and they removed them for the improvement of the stream.
This is supposed to be a shitpost stream; not a political stream. There's a clear difference between shitpost memes and political memes.
If they wanted the stream to have difderent topic/post criteria, that would be one thing, but they want it to remain a shitposting stream while adding politics, which are almost complete opposites.
