I use metric when I have to. Usually most of the time. However, I got standard and metric tools. I buy japanese cars so I usually use metric. But I'm very used to miles, gallons, inches, pounds, pints, cups to give a shit if it bothers the rest of the world. I also don't mind imported stuff that only has metric. I can also look at stuff from India and other middle eastern countries. My parents had a Buddha when I was a kid. Probably chapped the hide of the fundies. I think we can learn a lot from each other.
