The notion of "objective reality" is quite a thorny one, especially if you study Consciousness, Depth Psychology, Quantum Mechanics, Symbolism, Hypnosis, Postmodernism, etc. So, if that's your orientation, it would make sense that we wouldn't easily see eye to eye.
... That perspective has a whole fascinating and insightful world behind it, your world of experiences and network of semantic associations and understandings. But there are so many other worlds too that I value. And ultimately, these worlds aren't separate, and the only way we'll know what happens when they crash into one another is understanding all of them.
One difference in my approach is that I actually don't see Socionics as one thing. I think your version of Socionics might indeed be quite simple and clear, and maybe people will be able to see that. But, each approach to Socionics isn't for everyone. I think that people, because of their innate orientations, might value different approaches to typology.
