Why do so many individuals ask such silly or stupid questions on Answers?
We have a lot to learn in our lives, and one of the things that we have to learn is that there are all kinds of people in this world (and in YA), with different mental abilities, different knowledge levels, different approaches, some serious, some funny, some stupid, etc. The experience you have cited is commonly felt by a lot of people on YA and there is nothing you can do about it, except to ignore such questions. When I read a question that falls in the category you have mentioned, I have learnt to just skip it and go to another. This way, I have learnt not to lose my sense of balance in YA!
