Now I look at telemarketers a little differently. I had a telephone line installed and purchased a phone for MY use. Not for ANYONE else's use. When I give my number to friends, family or anyone else, I am giving them access to my phone line.
Compare any other utility you pay for. How would you like if your neighbor hooked into your electric meter and took electricity you are paying for? How about if someone stopped by and ran a hose from your outdoor faucet to a tanker truck and took a few hundred gallons? Whats the difference? They are all utilities that are paid for by the owner or subscriber.
I don't look at employees of telemarketing companies any differently than I would look at an employee of someone that sent you out to borrow my car without my knowledge or consent. Other folks may not agree, but I look at it as theft of services. In order for you disagree with me you would have to come up with a pretty compelling argument as to why you should be able to use ALL the utilities that I pay for.
You are using a utility that only I pay for. What gives anyone that right?
And as far as being concerned as to what I am teaching my children? That's precious. I couldn't care less what they say to a telemarketer.
