I used to manage telemarketers. I can assure you....your comments and what not are just a bump in the road. They not only don’t get to “corporate”, they don’t even get marked down. The machine just connects to another caller.
It’s best to just hang up on them. They care about making a sale. That’s all.
That's the short method. Long method: keep them hoping for 10 wasted minutes and THEN tell them you're not buying because of their anti-rights stance. Time is the only commodity they have to sell. Alternate short method: air horn.
