I'll ignore how ridiculous that is for a second, because now I want you to explain why it is we aren't dead from all the amines in our body. That includes every protein present in our bodies and all of our DNA, as well as a very large number of other biomolecules I'm missing out because the list is too long.
Also, you should answer IA's question. What about peroxides?
And heck, while we're at it, you could try explaining why H2S is toxic. It has two lone pairs as well. Then we can move on to...oh, I don't know, let's start with Sarin nerve gas.
