What if it is neurogenic pain?
I.e. pain due to your nerves being f**ked up rather than anything else being f**ked up? That's analogous to the critics being the "unhealthy state of things". Example: Hate speech.
Well, I suppose we need to identify the cause of the pain before we can start to administer medication. If the pain is clearly an irrational response, then certain parts of the brain can be altered to relieve the body of such distress, but a universal immunity to pain is never the answer.
Translation: if the hate speech is unfounded and unjustified, then a request can be made for this person to be silenced regarding that matter, but we should never prevent him/her or others from expressing their views on other matters, even if they choose to do so in very politically incorrect ways.
