It's just that you're talking about such a wide range of human irrationality. When will it end? Only after the apocalipse. As a species we are intolerant, by our very nature, of others who are by perception or reality different from us. That's not to say that an individual can put that behind him and actually break out from those tendencies. Most humans can and probably never will be able to break through that boundary.
And you got your title, if memory serves, for posting a bunch of really off-the-wall topics, not because they were hard to understand or anything, but simply because there was no apparent motivation for bringing up the subjects in the first place. Much like this thread.
