I'd be curious. Try it: Next time you lose, say "Nice game," and something specific and complimentary about how they beat you. Then ask for the rematch. I'll bet you get more rematches.
That really may make all the difference. People who are trying to quickly soothe a bruised ego are less likely to show basic social courtesies.
I usually decline rematches (I'd not want them to think we're going 'steady').
