As a matter of style and politeness and adherence to the Physics Forums global guidelines, one should avoid criticising posters and only criticize postings. Verbiage such as "deliberately pedantic and arrogant" may be straying over that line.

If you want to hit someone hard "you clearly don't understand' is polite but to the point. I think the mods do quite well with the more objectionable visitors, in fact. They don't seem to hang around long - or oerhaps they come back in another, more polite guise.
