warped records damaging?

I read that warped records can damage your system. how so?
My cartridge goes up and down with the warp, sounds OK.
This will cause wear and tear on your canteliver and boot. Shortens cartridge life. I have the VPI periphery ring which eliminates record warps. what a revolutionary advance in turntable technology!
I wouldn't worry about playing a warped record on occasion. I've got one or two that deflect about 1/4". If your arm and cartridge track it without flying out of the grooves, I wouldn't sweat it.

One thing I would watch for is extreme woofer pumping caused by warped records. If your speakers are close to being a heavy load on your amp you could experience clipping.
