No matter what subject is taught, not every instructor is a good instructor, or lives the subject they teach. My father had a saying, "Learn one thing every day" . Learn something from every person you can, but make your own decisions, make rules for you.
who qualified the qualified who qualified the qualified ect .. was someone just born as a qualified instructor to qualify the rest ? LOL ..
.. LOL ..
Much like a college degree only proves you can meet the prerequisites laid out in front of you.It takes more that knowing the source material to teach. Sadly I also think shooting is much like riding a bike. Once the training wheels come off and your on your own most skill development comes from practice.
Knowledge of the source material doesn't mean you're qualified or capable of teaching it.
@GOPerfect my favorites are the wealthy tactical Timmy's who have gone to so many classes they think they are qualified to teach.
