Agree with avoidance is the best defense in any situation.
Disagree with not being able to defend against a gun.
There are situations involving firearms where not having one is a no-win, but just because someone brings a gun to a fight does not guarantee victory.

If you choose to pack a firearm, get qualified training and practice. The learning curve is much shorter than martial arts training. You may want to take some self defense training but you must train to be confidant.
Get some good Mace or pepper spray. Buy a few. One for target practice. Hide the others in easy to access places. Spray and run. Remember, some drugs will negate the effect of pepper spray so screen, screen, screen.
