The phrasing of not preferring the genre "at all" and of the fans of the genre being a "mentality", came across as less than enthusiastic.
Of course, you dont need to pretend to like a genre. Heh. I myself am less a fan of the postapocalyptic genre, which I occasionally accuse of being intellectually lazy for refusing to comprehend what an advanced technological society would look like.
At the same time I know there are fans of the genre, and some stories I do like, like elves of Shannara and Thundarr the Barbarian actually are postapocalyptic. There is much I like about Dark Sun, and if a bit more hopeful, a viable means to heal the planet makes the overall setting appealing to me, despite being postapocalyptic.
