I do not believe that this is an instance in which an extended taboo facilitates better understanding. Particularly if you go as far as to insist on tabooing even 'pain'. It is true that if you 'taboo' for long enough you will end up with a reductionist technical explanation of physiology such that applying moral evaluations of any kind seems inappropriate. Yet given that the meaning of 'pain' is rather well understood this obfuscates discussion of values more than it helps.

It is also utterly absurd to insist that your opponent taboo 'suffer' and 'pain' while you yourself throw around "subjective experience" as a more appropriate alternative.
