Agreed. You'd have no choice but to. If you roll over even once, you open up the door to many future attempts at the same baloney. The funny thing is they're usually lawyers or have a lawyer family member, or are just a lawyer wannabe who should know better, but hubris gets in the way of common sense and they waste their time and money anyways.
You can use a good CDRP win anyways. Its like having skulls mounted on stakes leading up your driveway. Its a major "proceed with caution" message, lol.
