You're trying to answer two questions, so that we could continue our conversation.
Good luck!
I never claimed people to be shot systematically nor that I know people stupid enough to have themselves shot because they refuse to comply. Just that there is threat of physical violence, and use of violence if you don't pay your taxes. If you try to defend yourself against that form of violence, you will, depending on the situation, face a gun sooner or later. So your point is not an argument against mine, that you will end up suffering physical violence when you refuse to pay your taxes and defend yourself against those trying to force you to comply.
I'm pretty sure you don't personally know anybody that got shot by Stalin either. That doesn't mean that Stalin didn't use violence to make others comply.
Good. Thus far we've established the following:
1. No one held a gun to your head.
2. You do not personally know anyone who had a gun pointed at his head for nonpayment of taxes.
Now if you can just answer the second question, we can continue. Concentrate. Good luck.
