Nope, don't see it, sorry.
I'll tell you what I do see.
I see far more risk for me and other car drivers on the road. I see evidence of increased cancer cases because of experts messing with chemicals, herbicides, pesticides and and releasing radio active material all around this globe. Not to mention the bloody virus!
But I don't see folk blowing them selves up with 4f .
Now, if it helps you get through the day in your belief about 4f is bad juju inside a gun then so be it but please please refrain from telling me or others that we have it wrong.
But! By all means find us evidence of, your words! " Damage or injury".
