Because...men...deserve to be rescued less than women...so if they were men, then they shouldn't have been rescued?

That's the most screwed up logic I ever heard.

Also, considering the mass chaos surrounding the Katrina evacuation, I don't think women and children were exactly evacuated first. I didn't hear a lot of stories of men "being all heroic by staying behind." People tried to stick together with their families and look after each other. This wasn't a sinking ship, it was a city. I'm pretty sure that the rescuers rescued whoever they found.

And if the news story is true (see above thread re: Onion) then I think that no, there is no good reason that you could come up with for that sort of action.
