I presume you are talking about this question.
In case you were not aware, the StackExchange group of sites are not general internet chat style forums, they are Q&A sites. More specifically, they are Q&A sites aimed at producing definitive answers with a low signal-noise ratio. This is one of their key differentiators to other sites.
The example question in its original form was a bit of a doozey, breaking a few of the question guidelines, so the correct action was to close it. In this respect Sabyasachi is no more special than the thousands of other new people to the SE network who have made the same mistake. In fact his experience here will carry across and benefit his interactions on the other SE sites he is also a member of. His status as a new member might grant some understanding and sympathy towards the state of his question, but it doesn't excuse the question from regular community moderation.
The correct action for you as an established member is not to whinge and argue about it and try to get the rules/guidelines changed, your responsibility is to edit the question into a manageable state, or encourage the OP to do so themselves.
Edit:
this is to answer some of the points raised by Robin in the comments:
Someone new to martial arts asking for advice is someone who could potentially ask more questions over the years, significantly contributing to the content of the site.
Agreed. However their question must still fit within the framework of the site they are on. The fact that that question has been through 8 edits and was reopened is testament to the effort some people are willing to put in to save a question. If Sabyasachi is visiting anywhere on the SE network he will have been notified that his question has been reopened and has received answers.
created by people who don't understand enough about martial arts to be able to answer certain questions, so they choose to ban those questions rather than let people who know more than they do answer them.
Ouch. That comment makes it sound like you a) have a massive ego, and b) have personal issues with one or some of the members. Is that the attitude you take into the dojo with you?
I was around when this site was first proposed, I was there when there was a lot of discussion about what would or wouldn't be on topic. The rules and guidelines of this site don't mean that a question like "What's the best martial art for xyz reason?" shouldn't be asked, they simply mean that question shouldn't be asked here unless it is very tightly constrained to avoid 20 different answers all equally correct in their own way.
The rules and guidelines should be changed, they're flawed on several levels
Granted, it is harder to make a subject like martial arts fit within those guidelines than a subject like programming. Individual communities within the SE network can and do apply their own interpretation of the guidelines to fit their subject matter - the guidelines still exist, they just may not be as rigorously enforced.
But to get to the point: if you believe there is an issue with the way the guidelines are administered or with individual questions/answers, then by all means raise it here on Meta (like you did). But it is imperative that you do this in an even-handed and complete way. Lay out the problem, ask a question, propose a solution. Be critical, Meta is the place for that. But don't just make a couple of statements and end your question with a dire Try to argue your position all you like. MA.SE is going to get shut down at some point if this doesn't change. - with that your question is little more than a rant.
