Well I don't see how can someone be for blu-ray, because back in DVD & VHS days you went to video-store and borrowed it, but now that video-stores are gone you have to buy blu-rays if you want to watch them and I think I never bought a single VHS for instance. Not to mention that for some reason (probably fees for Sony) blu-rays are much more expensive then DVDs.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
