The fact that you have felt something your whole life is not to the rest of us much of a reason to believe it. Nor do a few examples of analogy failures give much of a reason. Yes of course it is great to try to understand things as much as possible, but noticing and paying attention to similarities is a great tool for doing that. And what to you may seem "surface" similarities can to others be understood as causal structural similarities if they understand abstractions that you do not.
