It means nit-picking needs to stop. If you read the whole novel, I'm drawing a clear line. Breaking rules is 100% not cool, but there are cases when we are a little bit in the gray area, everything's not black and/or white, there are cases in which facts and personal preferences meet, when asker needs directions to act. Example: asker is dumb, asks a question, needs quidance. It can be done a dumb way or a smart way, but that's an opinion right? Not for the asker (maybe because he's dumb) or no, he wants reasonings on what to do and make a decision based on that. It includes opinions what should be done but also facts that doesn't depend on mind. I see this case that an answer is a little bit opinion based, but the question wasn't.
