Ok, let's break this down.
Combative personality. No, perhaps objectionable to stupidity. It's not fighting it's discussing, what are you? A shrinking violet?
Spotting someone who can't fly. Well, not many people can until they are taught to do so. Like I pointed out, and gave an example, just because you are nervous doesn't mean you can't fly and go on to good things. Perhaps you couldn't teach, or couldn't be bothered.
Maybe someone will give me a personality. In your very first sentence you told everyone that I had a personality. Which is it?!
