Again, you have this fallacy that libertarian thought is concerned about self and nothing else. This is incorrect. A violation of anyone's rights, my own or another's, should obviously be opposed.
No, I'm not attacking libertarian thought at all. I'm asking you to provide justification for your philosophy. You say "should obviously be opposed." That isn't obvious as many people don't have any problem violating the rights of others. Why do you think it should be opposed?
Shalom.
