I mostly agree: I just think you are taking this attitude too far with the example of the MBA, unless you very consciously included that word 'constantly' there.
If I'm the only one in my company that does martial arts, I can expect jokes about having to be careful when having an argument with me. If you have a nest of pet snakes or always cook the same lunch or have an MBA, you can expect specific jokes, when contextually relevant. These things differ from being Asian or a woman in the fact that they are choices people made and that these choices can be considered reflections of this person.
Of course you can take the pointing out of such differences too far, to the point where it seems you feel this person is defined by a specific difference, as you constantly point it out. In acceptable quantities, making jokes and laughing together is quite healthy and it would be a shame to do without, even if you are yourself the subject of the joke.
