Know they had to take Superman out of the equation, but seemed like another silly point. They've got a device that blocks the signal, right? Couldn't Kara just go slap one on Superman and double their numbers? Seemed odd to just shrug it off and say he's lost.
Also, would think that in their 'nature vs. nurture' debate there, nature would have to win. He THINKS of himself as more human, but the brain and wiring is still Kryptonian, so either the signal should affect both races, or neither. Doesn't matter if you think you're a dolphin, if you've got a human brain and that's what the signal is being broadcast at, you're sunk. If it's ignoring kryptonians, growing up on a farm shouldn't make you open to it; it doesn't make those changes...
