Compared to the Old Testament, the cultural and historical contexts of the New Testament are much, much less nuanced. So when critics of Christianity pull stuff out of their asses and start quoting the Old Testament left and right, they’re being super disingenuous. Not only do they fail to analyze the intricacies of Christian theology, but they also fail in their awareness (or lack thereof) of the relationship between Christian theology and the books of the Old Testament. IE do these critics know what it means when Jesus is referred to as the Lamb of God and what the implications of such a title are? What it means for Him to be the Great High Priest? What it means for Him to be the Son of God? The Messiah? All of this is essential when it comes to explaining the Old Testament through a Christian lens. Christianity is not simple, nor is it easy to follow, nor is it easy to understand. I’m not sure why it’s claimed to be otherwise.
