Stop trivialising it by calling it juggling.
What do you have against juggling? Contact juggling (sphere play?), diabolo, devil sticks. . . they're all a form of juggling too, and they take a considerable amount of skill and practice to be any good at.
To me, a good contact juggler is a lot more impressive than a good flourisher, and is more entertaining to watch. When he or she is using an acrylic ball, it looks like the ball is floating, and the performer is moving his or her body around the ball, rather than the other way around. It's practically magic in itself, except giving away the method doesn't spoil the trick.
When it is really broken down, flourishing is, by and large, another form of juggling. And there is absolutely nothing wrong with that. I don't understand why people seem to think that there is.
