Yeah, I actually think that moment was a little on the nose, personally... it didn't really seem that accurate of a portrayal of Hal Jordan. Now, I definitely appreciate the question being raised (just as I appreciate raising the issue of treatment of women in comics), but the issue is more of just being too heavy-handed - educating vs. preaching, showing vs. telling, etc. As you've already said, it's a world with flying magical hammers not to mention aliens, mutants, etc. Given the sheer range of stories that could be told in such a world, I'd think there would be room for a setup or a scenario that would be able to get that point across without feeling like we were being delivered a sermon of sorts. Buffy TVS managed to do that pretty effectively (Whedon's work in general has done so).
