People do have the right to defend themselves with the minimum force needed to repel the attack, and only as a last resort.
When did I say that people doesn't have the right to live? Please stop putting words in my mouth.

We now live in the real world where there is IP legislation.
You infringe, I find out, I send you a notice, you ignore it. You are now the agressor. I had a rightful claim that you ignored. And here you decide to go to the monopoly court, who will interpret their monopoly laws and use their monopoly on violence, escalating this violence until BitterTea complies. If money can't be extracted by any other means police will show up at your door, as a last resort. If you start shooting at the police you have a problem, as they have the right to defend themselves. Again, with minimal force.
However if you are a normal member of society things will never go that far.
