I was merely illustrating how a scenario you have described as contrived, nonsensical, and self-inconsistent could be seen as the opposite if you weren't so adamant at preloading your arguments with words like "nonsensical", "invalid", "clearly", "perfectly", "lazily", "obviously", and other kinds of implicit argumentation boiling down to "anyway, as I said, A = B", because, as you may have known, there are things notably less contrived than attempting to poison somebody with a "non-toxic" substance whose LD50 for humans is estimated to be at least four orders of magnitude lower than that of water when ingested orally. (See Erowid sources
here and
here for your future references; and yes, you should have noticed yourself how LSD makes your breath heavier as one of the first effects of the onset.) In a criminal setting involving an expert chemist with murder intent, a message to send out to, and every prerequisite to synthesize the needed amount, that actually makes quite a bit of sense, and is actually pretty original as far as poison is chosen. If you think that doesn't make sense, you should get out more and notice how there are things happening everywhere around you that make even less of it.
The target audience of HP (read: those who are supposed to enjoy it) are people who don't ask many questions, are easily pleased, and don't expect clever art-house from a fairy tale setting involving prepubescent boys and girls in a world of magic. It doesn't make it better, but you could have dealt with it already instead of writing dissertation-worthy commentaries on why and how it's bad, which indicates how you apparently have a lot of free time to burn the valuable resource of brain activity on something as important and healthy as a similarly empty game of arguing opinions on the internet. All of this leads me to the following conclusion:
— “Your words are as empty as your soul!”
Now, may I suggest going and doing something more useful with that marvellous intelligence of yours? :}
