Given the violent proclivities of our Lefty friends, being a mite circumspect about speaking to strangers on the telephone might be a wise precaution.
I buy into your logic. We really do not know who is on the other end of the line or what their motives really are.
I do not answer the phone unless I can ID the number.
I’ve been contacted by Gallup twice in the last month on my cell phone. No idea how they got my number. I politely refused to answer any questions and hang up. You are correct about it being a wise precaution. Do not have your name or phone number connected to being conservative. I don’t do yard signs or bumper stickers because the left is violently unhinged. I know there are millions who think the same way.
