I do not generally [consider deleting, or move to beginning of sentence] hold people in contempt because of for their profession, their job**,** or their calling. But copy editors editing!

Not as bad, I will grant, as war criminals or child molesters, they nevertheless belong in one of the very lowest categories of human intelligence**,** and indeed morality. You will [consider ‘may’] object that copy editors perform a most useful and necessary function, turning what is often ill-formed and error-strewn text into something more presentable. This, too, I will grant. However, it there is no excuse for what copy editors they [referent is clear] also do - which is to [run-on; consider breaking into two sentences] interfere with people’s painfully-crafted stuff [lazy choice of word] when there is no reason whatever for doing so, other than some quirk in the ^mind of the particular copy-editor ing mind which is at work.
