Oh I'm quite used to it. I often have trains of thought that people find to be strange but sometimes I find something that I deem to be worthy of thinking and get met with the same response anyway. People are weird.
People get so set in their ways that they don't consider other sides of a subject. They look at it their way, accept their viewpoint, and move on but don't bother to look at it from another angle, even if that means sparking an argument.
