I have to disagree with the statement that you cannot injure someone you know.

No, dianavan, I did not say that. I very precisely phrased it as "You can't kill or hate a person, only an object." If someone is made into an object, whether by politics or by you, you can hate them and/or kill them. If you know them you cannot hate them -- although you could know them well enough to make them an object.

Sometimes you have to injure someone you know and love.
