What means subjective here? Is it really a question that is subjective or the answer I'm expecting would be subjective?
I can't really speak for the commenters, because I can't know for sure what they meant.
However, I share the opinion that there is no such thing as a subjective question. Or rather, all questions are subjective. Simply because a question always stems from personal experience.
So I'm guessing the term 'subjective question' is being used as a shortcut for 'a question that invites subjective answers'.
And why subjective is bad for this network? Don't subjective things have any truth and don't they help the person who is asking question ever?
Subjective isn't necessarily bad or banned. We do allow critique questions, which always invite some subjectivity. And of course the subjective opinion of someone with years of experience is valuable.
The issue with subjectivity is that it easily degenerates into a it-looks-bad-no-it-doesn't kind of argument. No one wins in these types of arguments.
All in all, we try to balance on the edge of a knife: try to acknowledge some subjectivity is inevitable and even valuable, while also trying to avoid the yes-no type of arguments that are just destructive.
