Is anyone else getting culture shocked by California's Prop 65?

I am an avid firearms, knife, and fishing guy.
Since prop 65 protocols have been slowly integrating into consumer products, I’ve been relatively surprised to find out that just about everything metal, seems to be potentially carcinogenic and/or cause reproductive harm.
I don’t know if it’s just a coincidence that materials used in my lifestyle are more likely to have these warnings, or if everything is made of poison.

I’m aware that lead is used with ammunition, and fishing weights. But, there seem to be ingredients in protective/corrosion resistant coatings on a lot of metals that have the warnings on them.
I did an extensive search on most of my knives, firearms, and other items that I commonly handle. The results were, pretty much everything I handle has the Prop 65 warnings…

Does it surprise anyone, that so many items are potentially harmful?
