There is some Native American blood on my dad's side of the family, I am 1/8 myself. Besides that, we're all pretty white, a big mix of lots of things such as French, German, Irish, Danish, Norwegian, etc. Strangely no one has really married another race as far as I know. We had an extended family reunion a few years ago and the one adopted child of another race stood out very obviously.
Religion is all over the place, most of us seem to be atheist but in general it's very much a "don't talk about it" topic, so I can't be sure. I do know that one of my great-grandmothers was a Christian pastor, an aunt and uncle are Jehovah's Witness, and my parents recently converted to LDS.
As for sexual orientation, they all seem to be straight or at least not openly sharing otherwise (and why would they, honestly the topic hasn't come up that I can recall).
In terms of politics it is pretty evenly split, with a few more liberals than conservatives I think.
So I guess my family isn't very diverse at all. However we grew up in a very diverse place and I now work and live in some of the most diverse places in the country.
