My family's Christian, but hasn't been really big on church going. My brother's and I are Atheist, which deeply troubles my grandmother and bothers my parents, but it's not something we talk really talk about. My sister's not Christian, but she she believes in something. No one really attacks anyone, (except for the usual sibling disputes you get with 4 kids in a family), and we all get along fair well.
I take that back, the Jehova's witnesses that come by every once and a while get attacked with Science generally. The last time they came, they caught my sister and she taught them about evolution and how it fits into intelligent design. They seemed... incredibly shocked, somewhat worried, praised my sister as a scholar, and haven't been back in several months.
But yeah, that's more or less where I am.
