SDC, as far as I know, is the only Self Defense company that offers its online students the ability to receive a private lesson from a Certified Instructor in the comfort of your own home in our Private Training Portal. This is going to revolutionize the self-defense training world.
The concept of Kill or Be Killed is not a new one by any stretch of the imagination.
Another thing that is not new is the other guy thinking you are a wimp. Hell, let him think whatever he wants, as long as you know what your abilities are then what someone else thinks is totally irrelevant and should not matter.
True self-defense is all about intensity. In the real world, on the street, it is either kill or be killed. There are no winners or losers in a street fight, just survivors. I choose to survive, and if that means kicking the snot out of an adversary then so be it.
