Left-hand politics.

I know this sounds weird, coming from someone from both sides of the fence, but I really do think left-handers are like Mac users, in the sense that they think that they're unique and better than everybody else.

Now, before anybody from both camps pelt me with food, think about it. Lefties always extol the virtues of being a left-hander, like being smarter and more artistic. But you never see a right-hander boasting about being more logical, do you?

Likewise, a typical Mac user utilises every opportunity available to talk about how their aesthetically-pleasing machines run faster and more efficiently than an equivalent PC, whereas Windows users...wait, there are no redeeming features for Windows.

Mac users and left-handers are also similar in other ways. For instance, you always see lefties go looking around in class for other people writing with the same hand (I'm afraid I do that sometimes) the same way someone with an iMac looks around at Starbucks for people carrying MacBook Pros.

These characteristics can be shared with people of/with other things as well. In fact, I wouldn't be at all surprised if 95% of the world's left-handed people are also either Mac users, DSLR photographers, Citroën drivers, artists, French or various combinations of all of the above.
