This is the first time ever someone blames me for Holocaust denial [0], but I'll give you another example then. If someone breaks into your house and tries to kill you, you might want to kill them too, but it's a little funny to say that there's symmetry there because "both want to kill each other!".

[0] to remove any doubt, I am not. I'm not sure how you got there, but I would insane to deny an event the took the lives of many from my family.
