Not buying that for a minute. My folks came from far west texas and my dad killed every rattler he saw and insisted everyone else do the same
I think i killed north of 100 by the time i was a teenager and out there they were agressive as hell
He and his dad wore stove pipe tin over their boots every time they went out in what passed for pasture and got struck who knows how many times.
Correct a Lot of modern people in the US have no idea what it is like to live among dangerous critters on your property.
We have been sold a bill of goods with the idea that these critters well only attack when you bother them.
They want you to believe that it is always the humans fault.
They want us to forget thousands of years of history.
