What is right or wrong, good and evil, love hate? Nothing more than personal opinion.
That's great news to me, because I'm looking for someone to kick in the teeth and ask for another. If it's merely personal opinion, I want you to tell me that when I prevent your freedom to speak. I want you to remember that when I break into your home and steal your valuables. When I'm forcing my will on you, tell me your disagreement with the situation is only your opinion.
Don't you dare tell me its "evil" or "wrong".
"I thought that stuff was all just opinion!" will be my reply. "What right for me, guy, is too tie you up and throw you in the river! What's your opinion about that?" Why would I care if its only wrong for you?
You said my way of thinking is foreign to you, well, I understand your thinking very well. You can't backup the things you say. If I were to prevent you from speaking, you would most certainly be outraged. When it happens, try telling yourself its only your personal opinion. Your suggestion of: what's right, wrong, good, evil? - will be far from your mind. That I guarantee.
