Yes, they write as if it's common sense (which isn't, as some don't have it) that when people generalize (of course, not all people), and that everybody understands (well, not really everybody, but many) that all things have exceptions (well, not all, but many. Some things don't have exceptions, e.g. some mathematical axioms), but it's still useful (except when it's harmful of course) to generalize for the most common case, and not give a laundry list (of course I'm speaking metaphorically, I don't refer to an actual list of laundry items) of exceptions every time we say something...

It's obvious (well, not to everybody, but to a certain large number of people) that instead they should include the cartesian product of all possible exception as extra qualification of their statement...

And God forbid (not actual God of course, as he don't exist) that somebody writes something like "Alaska is cold" when there are places in Alaska, like the inside of ovens and saunas, that are objectively quite warm (though, of course, not as warm as the Sun)...
