Right back at you. Do you seriously run away?
Is that your response to any situatuon that includes potential danger?
That being said, if your back is against the wall you have every right to defend yourself.
If you are in a life or death situation it might make sense to arm yourself and encroach, but if someone is breaking in your front door and you have access to an exit you are not yet in a life or death situation. Arm yourself and attempt to flee.
If you don't have homeowners/renters insurance, live alone, value your property over your life, and enjoy high risk life or death situations - then by all means charge on in. Just make sure you don't shoot your friend who you gave a key 8 months ago stumbling in from a night at the bar.
I'm not asking for advice.
