Ubiquitin – he might not consider the opinions of anonymous posters in the CR to be valid answers to his question. Which is why I suggested he look into the matter himself.
In any case, the main issue is what I wrote above: “It doesn’t hurt to be polite”. This is especially true when you are disagreeing with someone. You should always try to do it in a nice way. If you can make a point in a nice way or in a mean way, why not do it in a nice way?
Don’t you think the CR would be a much nicer place if people tried harder to be polite to each other?
