The OP is a little confusing, to me.
First of all "Buddhism" is not a monolithic bloc. It differs greatly from tradition to tradition, country to country, institution to institution. Thus one's mileage may vary when it comes to what "Buddhism" is "about", based on these differences to say nothing of the points that individuals choose to focus on. One video cannot be seen as being representative of "Buddhism" as a whole, or even Theravada or Thai Buddhism. Thus the question being asked here strikes me as misplaced.
That said, based on my experience I would say Buddhism is not about threatening people with anything. It's about cause and effect. Actions (karma) have consequences (karma vipaka). Truly understanding this, and using this understanding to cut off the root of suffering, is what Buddhism is "about". Everything else is just window dressing.
All compound phenomena are like a dream;
a phantom, a drop of dew, a flash of lightning
That is how to meditate on them
That is how to observe them
