The M25 not withstanding, speed limits are a fixed point on a continuously variable scale. They do not vary with weather conditions. If you drive at 70 miles per hour in driving rain, black ice, snow or fog, you cannot be prosecuted for "speeding". Undue care, or dangerous driving are possibilities, but not speeding. There is no analogy there.

or to arguments based on premises with which the author disagrees.

Turn that around. I am being told to stop pursuing discussion that I find interesting, relevant or important because one (or some small number) of others don't share my opinion. One persons opinion is to be overidden in favour on one (or a few) other opinion. (And even those few cannot find agreement.)

By that "standard", about (guess) 30% of the threads here should never go beyond 2 levels deep, because I'm not interested in CGI. And that would be a nonsense. Despite that not so many years ago, in some other Perl forums, "conventional wisdom" had it that questions and discussion relating to CGI were "not interesting" to serious Perlers, and so were fair game to ridicule and censure.

Take this right back to the top of the thread and we're right back to the same question. What is "aggressive argument"? But more importantly, who gets to decide.
