It makes perfect sense. You just lack the intellectual integrity to admit it, or the intellectual capacity to follow it.
You are saying, in effect, Jonathan Pollard bears no responsibility for betraying the United States by virute of the fact he is genetically more like the average Israeli than the average American.
It doesn't work that way.
If he wants to become an Israeli, all well and good, but he was born, raised, and aculturated as an American. There was no genetic imperative for him to act in the best interests of the Israeli government instead of the American: he just wanted to.
Similarly, Jamie Lee Curtis was born, raised, and aculturated as a female. Why? Because she's female!
The only reason the genetic argument appeals to you is it allows you to dismiss critics by challenging them to chase down an esoteric rabbit trail, the broader implications of which you don't even understand.
