Why should one be forced into "getting out of" his residence?

You're not, in the UK. There's a general "duty of retreat" - if someone gets
in your face and shouts insults, you're expected to back off rather than hit
him, and if he pursues then his intentions are obviously hostile - but it's
accepted that once in your own home you've run out of places to retreat to,
and should not be forced to flee.

I gather that doesn't apply in some US states, which is interesting.

Some? Try ALL!!

It's no wonder that so many European countries are
exercising their "duty of retreat". If such a thing
is indeed a legal principle, I imagine it stems from
centuries of nobility/serf contacts, where the poor
sod must never respond in kind to abuse from a nobleman.
