I agree with rebdoniel here.
Yenta, I don't believe you thought through the matter before posting what you did.
We don't know Hashem's ways, and the Newtown, CT massacre is difficult to comprehend.
Also, the two incidents are not comparable.
In CT, an individual with his own free-will acted as he did, with the terrible results that followed.
In Sandy, on the other hand, Hashem, using His "forces of nature", orchestrated a powerful show of destruction that caused billions of dollars in damage without any weapons.
So to try to understand CT, one has to first understand the parameters of bechira.
But to explain Sandy, there is no immediately apparent factor of bechira because this wasn't bullets from a human's gun but rather water from Hashem's "nature".
So let's take what we do know.
This storm, Sandy, seems to have been a wildly unpredictable and major disruption of the "natural order". If one is perfectly objective, leaving any rights issues out of the equation, Toeiva marriage is, of course, the same thing. It takes a male and female to physically conceive a child. Men and women are "wired" differently, and children benefit from having two parents, one of each perspective. This is obvious, well known and clear, even from a secular perspective.
We also have Chazal who tell us that the only zechus the nations have is that they don't write a kesuba bein Ish LiIsh. This storm also happened right after we read about the mahapeichas Sedom, whose name is synonymous with the basic act of Mishkav Zachar.
Governor Cuomo also ran on the platform that he would legalize this abomination.
So, despite certain obvious questions, I certainly see why the Rabbis you quoted came to the conclusion they did.
