By removing one passenger, this captain assured a safe and peaceful flight for all by letting the rest of the pax know that he would not tolerate abuse of his crew in any shape or form.
I think you mean, "After his airline treated paying customers like scum of earth already, the arrogant four-ringer ensured such contempt would be continued."
Such a display would put me quite off VS. Might even consider voluntarily flying BA, as extreme as that seems!
Now if said passenger has said "About f
ing time, you f
ing thick c
t" I'd be more sympathetic. But it would appear he didn't.
