I said from the start that the argument you presented was fallacious, and all you did was present it, now, because you have no other argument, you're working on aggressive attacks.
You're on your own now. Bye.
You're on your own now. Bye.
It appears to me that you are attached to a position that you aren't capable of defending.
So since less->magically safer is true some point, the argument can't be made fallacious by asserting it is true. The worst the argument can be is unpersuasive (although it is persuasive - from a practical perspective there is a tiny volume of toxic waste, it isn't a reason to block progress).
But don't let that get in the way of a good pile on.
