No, I think you're 100% off, because this isn't a REBORN! forum, this is a One Piece forum, with a Reborn! thread.
An example that makes sense would be coming to Arlong Park and making a thread bashing One Piece. So, since making a thread bashing Reborn!, or Naruto (perfect, perfect example), or Bleach here would just get merged into the main discussion thread, it stands to reason that the discussion thread is to be used for discussion.
Talking about disliking a manga or talking about loving a manga falls under the purview of discussion. Every week, people come in here and talk about whether they liked this week's chapter and how it stacks up compared to previous weeks. That's discussion too. Ain't nothing wrong with expressing one's opinion in the thread it belongs in.
The only reason you have a problem with it is because you like the manga others don't. Dislike the bashing? Well then do I have the bread for you!
You're just over complicating things now.
I agree with everything you said, but that's still not what I meant.
I'll say it again and this is what I mean alone, nothing else!
It's pointless to just come post once saying word for word,
"Blank sucks fucking balls*".
With obviously no intention of mentioning why they think that, and no intention of having a discussion about it.
