When a man wants to disarm you, to take away all means of self defense, even to the extent of armor, when he even goes so far as making it "illegal" to resist his violence - he means to do you harm.
If you wait too long, he will be able to do what he wishes, when he wishes.
When a man is not bound by Natural Laws, the only defense you have is violence.
Never surrender your means of doing violence.
Here's the text of HR 378.
They are coming. They mean to do you harm.
