Fair enough. I'm an American born American who relishes language studies. I prefer British English in most cases.

In this case, to me, using [sic] reads as preposterous. I kind of like it, but it's definitely unnecessary, right?

Except this wouldn't amount to the BBC failing to use British English; they are quoting someone else's written text...

Why do they use the non-british word 'sic' then?
