No, did you look at the categories? There were (among others)

Human or might as well be human Character

and

Alien, but still pretty human

So you can be an alien in either category. But your degree of humanity determines which of those two groups you might fall under. Moth3r is arguing that he's human enough to be in the first, but I think you have to wear pants to be considered. I put him in the 2nd category, but do think he's perhaps in a grey area between.

I thought your chess example was an argument for #1. But I'm not sure it's fair to say he "plays" chess when his opponents are told to let him win, so I counter with #2.
