Seems justified to me. I typically just ignore the religious stuff my family/friends post, or block those sites that they share. Then again my Facebook "friends" list is very small, it is limited to people that I actually want to hear from. I have dropped lots of people over the years, though not due to religious content. I don't need to read eight or nine daily updates about the awful hairdo on that lady you saw on the bus, or how nasty your hot dog tasted.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
