I'm hanging around and find there is a lot of quarrel here, people debate different views about Stack Overflow, or if my question here is proper and so on. This kind of debate people have here confuse new users like myself, who are looking for guidance and clear rules.how to choose the answers for a newbie if there is a big difference in them?
As I said in the comments, this has been discussed. The main reason for not having another meta site to discuss this meta site (so, a meta-meta site) is that then we would need another meta layer to discuss that site, a meta-meta-meta site. And that would go on forever...
If you, as a new user, are confused about what is the "right" way to behave on Stack Overflow or Meta, I understand your frustration. The problem is, many times there is no "right" way, people just think differently, and can disagree about pretty much everything. You get used to it after participating on Meta for a while, but until then... well, don't expect a final answer on everything, listen to the different opinions, and stick to the one you agree the most with. Also, try looking at questions tagged faq, their content tends to be more consensual (questions only get tagged faq after some discussion).
If the quarrels are polite but energetic then you couldn't really ask for more, unless nobody actually answers your question. If the quarreling turns rude and personal then flag the comments as being inappropriate.
