You might as well be arguing that Coca-Cola and a Black and Decker power screwdriver are mostly identical. Yes, that's how stupid your argument is.
This is exactly what I said about your voluntary ignorance. Gun manufacturers are not immune from suit for design negligence or manufacturing defect. I've said this, what, three or four times now?If you put a product out there that does not have the safeguards installed that the manufacturer knows will make the product saver and guards again misuse, it could be argued that this is negligent. Try selling a car without seatbelts or a pack of cigarettes without the warning label.
The reason you're not getting it is because you refuse to.
Or, you're purposely making a dishonest comparison. Misuse of a gun, criminal misuse of a gun, would be the same as criminal misuse of a car, for which car manufacturers are NOT liable.
This is the last time I'm going around in this circle, so if you repeat yourself yet again -- and you might -- review my last few posts on the subject for your response.
