The munitions were not weapons, as your expert confirmed.
I do not accept they were "used against civilians."
I believe they were used to provide a smoke screen.
That is entirely consistent with the evidence.

It should not have been used for that in a civilian area.
That would be illegal, but because Hamas had illegally positioned itself in a civilian area, it is not straightforward.

I deplore the fact that they used it, but might feel differently if a son or daughter of mine died because they could not be screened from their enemies.

You have claimed without evidence that it was used against civilians.
Prejudice.
You have described it as a chemical weapon when it was not a weapon at all.
Demonization.
I think you even described it as genocide.
Wild, hysterical hyperbole.
