Sean,
There are times when we need you to keep your speed up on the approach (210 till the marker) because of faster traffic behind or we are trying to close up a gap or create a gap so that we can slide someone else behind you.
The key is if you can't do the speed "PLEASE" tell us and we will make adjustments.
As for this Captain, if he is trying to teach good procedure for flying a fast approach that is one thing, but if he is one of those pilots that only knows one speed and everyone else be damned, well, he may be on his way to becomming a statistic, and the bad thing about future statistic makers is that they usually take others with them.
When I as a controller encounter captains that only know one speed (FAST), the first time I may let it ride, the second time I may yank you out of the sequence and make you last and/or a supervisor may have a chat with the company chief pilot.
