I can't see any difference in principle between saying "we" on the Mudcat and many other settings. When you say we, we (sic) are always open to correction or to the comment "that doesn't include me"
But so many people seem to take things like this so seriously. Get all uptight and angry, and then blame someone else for the fact that they get like that and don't like the feeling.
I mean a light-hearted comment like that is hardly worth getting all het up about. If the worst we (sic) get called is "duffer" that's not bad at all.
Some might see it differently, but I beg to duffer.
