I thought it had enough justice to comply with.

To the extent that it is worth replying to such things it is worth replying well. A terse reply will tend to (in my personal experience) and in this case seems to have set you up for further sniping and will typically result in undermining your position independently of actual merit. I expect the net effect of this engagement to be (admittedly trivial) undermining of the credibility of your MWI lesson.

My own interest is not in the QM but instead that several (relatively) subtle rhetorical techniques related to intellectual and moral high ground manipulation and asymmetric application of norms that I would like to see less of are in fact being rewarded with success and approval. ie. You are feeding the <person who is not a troll but is executing behaviors that should not be fed>.
