No, it only supports one group's statements, and then when they run into a wall they can't explain, "evolution didn't optimize this." If it can't optimize, then why so many detailed traits in humans? Either it did or it didn't optimize. Your point is moot.
Natural selection only determines which mutations will be carried onto the next generation. It sets a "lowest common denominator" of sorts for all living creatures. It doesn't arbitrarily hand specific species specific advantages. The detailed traits in humans were the product of a long process of our species adapting to an ever-changing enviroment. Natural selection doesn't aim to make every single aspect of our lives easy.
Furthermore, even if anal sex without lubrication may cause injuries, that does not change the fact that it is, by definition, natural. It's physically possible, and perfectly natural neurological processes drive us to it. Whether it's morally good or not is another matter entirely. Something being natural doesn't make it morally good.
Your grasp of your arguments, and those of your opponents, is severely lacking.
