You seem to be making an assessment of shitposting in the forum overall rather than focusing on what is happening in the pushup's thread.
Yes, this whole tangent started by me saying "shithole" and "spamforum" and you saying "negativism" in response. I hope I was able to explain why I call this shithole a shithole.
As for the pushup thread, its contribution to the shitholiness is that a 180-page non-speculation thread in Speculation sends the wrong message, whether that message is "any topic is fine in Speculation" or "some animals are more equal than others".
