That is called in the world of logic, "tu quoque," and it is a very bad way to argue.
And yes, Harry Potter was ruined ever since J. K. Rowling set pen to paper to write it.
Aside my moral qualms with it (me being a Christian and all) H. P. Is a rip-off of LOTR and of Chronicles of Narnia. Some people have argued that Rowling was simply inspired by them, and not ripping them off. If that was the case, then we wouldn't see as many elements of those book series in H.P. as we do.
And, if she actually was inspired by Tolkien and Lewis and not just looking for ideas to steal, she would have seen the obvious distinction between what Tolkien called Enchantment, or Sub-Creative ability (power bestowed by God or a God-figure upon His followers to preform His will) and Magic (a means by which people attempt to use supernatural power to control their environment, which shows a deep mistrust of God, or the God-figure).
But she clearly didn't. Instead, she gave both the protagonists and the antagonists the same source of power (which strongly resembles Tolkien's definition of magic) and called it a day. And that doesn't make for a good story. You can't fight fire with fire.
And the symbolism, too! Both Tolkien and Lewis, when they were writing their respective book series, were extra careful with the symbolism that they used. Rowling wasn't. She wasn't careful at all with how she applied symbolism, which anyone with half a brain can tell you is extremely dangerous.
All that to say, Harry Potter is a hunk-o-junko. It is full of both moral and literary flaws. We as a human race should be ashamed that one of us wrote such a horrendous book series, with it's obvious lack of good original ideas, and twisting of the ideas of other writers who were actually good.
