That’s not the description of a stampede which would result in killing 100+ people, even if true.
We will probably never know exactly what happened, as we only have IDF- and Hamas-controlled reporting of it, both obviously heavily skewed.
But the claim that this is Israeli military simply shooting to murder 100+ people is to say the least obviously unsubstantiated.
I am not excusing anybody, I am just tired of the blatant propaganda with zero reliable sources.
What you describe is horrible, and also it is simply not real, but entirely the result of your imagination. No source claims any of this the way you describe it.
In fact the latest reports describe two separate events, one where the stampede occurred, with no IDF involvement, and another event where there was a shooting at a check point. There is NO way to know what exactly happened from behind the keyboard. At this point all your claims are only the reflection of your beliefs, and nothing more.
