Sure. If we're baking a pie and debating whether to use Granny Smith or Red Delicious, then the analogy fits. I'm betting you were going for the common "two things that are identical" angle though. Which is why you're wrong and I'm right (well, one of the many many reasons).
No, I think two different apples is fine. A reasonable comparison between to incredibly similar things that differ only slightly. As opposed to your argument that they aren't all simmilar.
Which is why I'm right and you're wrong. QED. One of, at this point, a number of examples that likely can't be counted as it progresses asymptotically towards infinity.

Your mother's a *****. You like to jack off dogs. That's right, you heard me. You like to grab that dog by the bone and rub it like a ski pole. Your dad? Gay. Your priest? Straight. **** off and let me post. It's not true, it's all in good fun. Now go away.
