The thing about MDMA is that it makes it almost biologically impossible to have a negative reaction to someone else's questions and comments. So we could get really deep without getting angry. If, for instance, one person says something provocative like "I hate your mother" then the other person won't just react, but will want to understand where you are coming from

Not very accurate. Especially the "biologically impossible" part. Psychoactive substances are extremely individual. There is nothing biological nor neurological happening that would induce a state that you say here. Increased activity of the serotonin neurotransmitter does not prevent negative reactions, negative behavior or anything of that nature.

I understand the point you're making but your phrasing is incorrect. And proper "education" and knowledge about substances is something I find very important.

And I'm saying this again, all psychoactive substances are extremely individual.

I would avoid anything that comes in pills or is crystally as a general rule

The hydrochloride salt of MDMA is in fact crystalline.

I'm sorry if this has already been answered, I looked for it in the comments but couldn't find it. For how long were you locked in? And how much could you do? You could blink and you say you could stick your tongue out for "yes", was that all or could you like twitch your fingers or something?

There is a lot of research on "choices" and "changing choices" and an overwhelming amount of them all seem to indicated that the "choice" and the "changing" of the "choice" all originate subconsciously and it is predictable in test subjects prior to it entering their consciousness.

I think, what we as a people need to do, is change how we view "us". When you say "free will", now, you are referering to the conscious "I". That's who "we" are. But the "I" isn't the brain, the conscious "I" is a product of the brain. "We" are not the brain we are a part of it, a small piece of a larger system, a system with numerous other functions that "we" have no part in. So our choices will be influenced by memories, by learned behavior, by the past, by the current, by the future, by experience, by stimuli, and while I don't believe that we fully understand how these subconscious functions interact and come together to form the conclusions, or choices, that they do, it is fully within the realm of possibility that the brain as the entire system has something that would qualify as a "free will".

It just happens to lie outside the narrow reach of our conscious "I" but the real "I" is the entire organism that we are and not just the conscious "I". So depending on how you look at it, you either do have agency or you don't but either way you look at it you are always going to make the "choices" that you "choose", so what does it matter.
