There are a ton of people asking questions who genuinely don't know why what they're asking to do is a bad idea. If you assume that they just weren't aware of the better way, you'll be right about 99% of the time. It's not a reflection on you, it's a reflection of the cluelessness of the general population. If you really just want to know about the internal workings of something, perhaps stating so up front would get some sympathy - but no guarantees.
