Can't stand the teen drama that is harry potter. It's no different than twilight, in my opinion.
I'd argue that neither is superior to the other, btw - but since we're on Hacker News of all places, it's quite understandable that there'd be a lot of Harry-Potter-loving nerds here! The comment above would be (rightly) heavily upvoted if it had been posted on a Twilight forum...
On what metric? Ah, intelligence? Productivity? Technology skills? Contribution to humanity's scientific progress? And who decided that those are the way to measure the superiority of one human being over another?
You say "moral relativism", but I don't think you've looked up the definition of that term. Moral relativism is about the evaluation of moral judgements and actions, not of people's intrinsic worth.
Fundamentally, you're only "better" than a crazy teenage girl according to metrics that you've made up. For example, if the ability to give birth to and nurture children is picked, you (assuming you're male) would be intrinsically "worse".
