I was a member of the FOP for several years (not by choice) and when they would call I would say I don't appreciate my own organization working against me on gun rights or supporting Bill Clinton for president.
Now I tell the American Bar Association the same thing when they call.
I make certain to get the org.’s name right. Then I tell ‘em to send me a letter, First Class Mail, and I will send them money (assuming it’s a worthy org.) Then I tell them in no uncertain terms that if I EVER get another phone call from them they will have seen my last dime. I then hang up — hard!
