No one from the Church of Satan
is going to follow you around to observe how you choose to interpret and implement these principles.
The point is that you agree with the principles.
If someone wrongs you, is it your first response to forgive them and make excuses for why they are that way (the Christian approach), or want to get justice (the Satanic approach)?
First, see the principle as a principle, before worrying about your imaginings about how you think other Satanists might put the principle in action.
If someone screws with you while you're out and about, just minding your own business, you might ask them to knock it off. Right? If they don't, do you play the victim, or do you have measures in place to take care of yourself? No one but you can look out for you.
If you have guests over, and one is really pissing you off, do you put up with it, or do something about it? It's your damn place, after all.
First, see the principle. Don't worry for now about the details of fine calibrating the response.
The beauty of it is that you are the only one responsible for calibrating what you need to do in any situation so that it works out in your favor.
Do you agree with the principles of seeking justice when wronged, being left alone in public and having the right to defend yourself when you are not, and having the right to expect your guests to behave as you wish while they are in your space?
It's really not complicated.
