Haha. I wasn't trying to be argumentative. I taught Government for many years and that question came up many times, even from parents. I'm used to explaining it that's all. I still get a lot of questions from folks and that is one that people don't understand until it's explained.
Not that I won't also debate someone on the subject also if they want to argue about it. Hahhahaha!
No problem, I take no offense, and it is a good argument, one that isn't easily solved.
Take war for example. I could make a case that it could be considered self defense on a grand scale, and there would be the moral argument to be made that it is still wrong.
No easy answers, that's for sure.
