I find the area of how language defines thought to be very interesting.

I remember being fascinated by the concept that the Romans couldn't deal as well with abstract algebra because of their way of counting, and (from a very limited perspective) I have found that phrasing things in French did change my own perception of how I thought.

I imagine that a German speaker would think a bit differently as well, due to the need of having your verb worked out and held onto until the end of your current sentence. I don't know if that helps to explain their famous technical and musical abilities or not, but it's an interesting possibility.

Personally, I'm not going to go changing my 'neuter' pronoun to being expressly female, as I have in the past felt irritated by those who do. It also makes insulting other drivers on the road (at least in my mind - I don't actually say anything!) less acceptable. Insulting a female is something I have to specifically want to do, and needs a good reason. Insulting another male, on the other hand, is almost expected...

See a BMW for example - think 'wanker'. Nice and simple. ;-)
