drive single channel of stereo amp


I have a dumb question,

I was told long ago that it is bad to drive an amplifier channel without a load on it. I never understood why. If you unplug the source left channel from the source to preamp is that still a bad idea to play the system with everything else plugged in? Why is it bad to drive without a load anyway?
Thanks for any help.

Thanks for the reponses guys. What I really would like to know is why the amp needs to have a load? What causes the damage if there is no load?

Thanks.
