Again, it seems that we are at two extremes.

To me, there is one stance - where your feet are under you and you are in balance to move. Your body knows how to do this, if you let it. Especially if you have any athleticism. Unless you are going to train all the time, worrying about that complicates matters. I have seen people hesitate, and leave themselves vulnerable. When we talk about it, they feel their stance was "wrong." I have even seen them look down at their feet trying to figure out what is wrong. This will get them hurt.

You do not need to go to the extreme of having a "front stance" or a "back stance", etc. You need to be in balance, and solid. Anything beyond that is extra, and if you want to be fancy, fine. My point was that you don't need all of that to be effective. We should not discourage someone from having a weapon for legitimate defense, and using it at need, simply because they haven't gone to that level of training. If they have played any kind of contact or movement sport they have enough stance to get by.

Sure, someone with more training will be better. But that is not to say that the average person should be discouraged from having something rather than nothing.
