LOL-that's true! I've seen the same thing. What I meant was that the person suggesting a fic for discussion not pick it because he or she thinks it's poorly written(and/or has bad grammar)and so would be good to make fun of. It doesn't have to mean that the person who brings it up has to love it,just not pick it so everyone can spork it.
Also,there are certain stories I read that I like,but I still question some parts of the characterization or plot. I have nothing against a critque of a story. I think that's what makes a discussion interesting.
