When you answer a question, that person who asked it ( and maybe the Mods too) can vote if it was helpful or accurate. Opinions are just that and some folks don't want to know the truth. They ask their questions here hoping to get validation for their way of thinking. Right or wrong.
Some people are complacent in their ignorance. They ask the question not wanting to hear the answer or even an opinion. They just want to appear to be open to other's ideas and speculations so no one can call them shallow know-it-alls.
