The topic at hand is centered around drugs that generate pleasure. You're a little left field with hallucinogenic drugs. I'm sure there's some sort of "profoundness" there as well but it's a different topic.
It's like saying the pleasure you feel when you eat a food you like isn't real.
Or the feelings you feel when someone kisses you aren't real.
Drawing arbitrary lines around what is real feeling based on the stimuli is very strange and usually driven by ignorance or fear.
Same goes for bonding, closeness and so on. You just tricked your brain into hallucinating emotional responses for things that are not there.
Salt enhances the flavour of food, MDMA enhances the experience that's already there.
It doesn't just invent the feelings, instead amplifies the feelings you have.
Is salt just fake taste?
If you think MDMA is giving you a feeling of deep friendship with a perfect stranger, then you might be hallucinating the feeling of a long and strong relationship.
However, that's not really the feeling you're getting on molly. It's more recognizing the preciousness of our shared humanity. If done with a friend or a lover, this in itself is a genuine bonding experience. If done with a stranger, you're not expecting anything more after the experience, but it still feels valuable.
Truth is just an expression. I use it in the same light as "profoundness".
I understand the stigma associated with the drug. But the emotions generated by the drugs themselves are in reality actualized by the brain and that actualization cannot be invalidated. It is worth it to ask, think and wonder about this actualization even when you have no plans around taking the drugs yourself.
