A theory can be "real" in the sense that people believe it, and also controversial because it has little consistent evidence behind it.

Nowhere in my comment did I attack you personally. I made an analogous argument; reductio ad absurdum. LSD is also a man-made synthetic compound, and promotes neuroplacticity. And if you've ever known a meth addict, you'll know that the substance can cause significant and enduring personality change.

You're advancing a pseudoscientific theory, and I'm ripping it on its utter lack of merit. Please don't take that personally.
