I certainly hope that no one thought we "passed the limit of being respectful"! While you and I clearly have different opinions on this matter, I feel that we both made strong points in favor of our respective positions without being rude to one another.
Despite the fact that I disagree with your point of view, I enjoyed our discussion in Perl: Survival of the Fittest and I feel that it's a good example of how people can legitimately disagree with one another, and even disagree at length, without being rude. Some of our statements were a tad strong and we may be accused of attacking each other's statements, but we never attacked each other. That, for me, is as far as such differences of opinion should go.
<HUMOR>But you're still wrong about COBOL.</HUMOR> ;)
