British and American English. What's the fuss?

You say toe-may-toe, I say toe-mar-toe,
You say po-tay-to, I say po-ta-to,
Toe-may-toe, toe-mar-toe,
Po-tay-to, po-ta-to,
Let's call the whole thing off!

So goes the song. But what about donut and doughnut? There was a time when I would strictly use only British spelling. These days, I'm not too strict on what I use. If I want to use just one or the other, I use the computer to help me, by setting the input language to British English and vice versa.

Donut or doughnut? Frankly, they taste equally good to me, so who cares? Hahahaha!
