One of the things that we as a genre community seem to be most vulnerable to is the idea that our personal favorite type of writing is the only type of writing that other people should love and pay attention to, and that anyone who disagrees that our pet subgenre is the one true form of worthwhile writing is a poo-poo head. This tends to be expressed in one of two ways:
1) I want more of my stuff, and why isn't everyone writing and publishing that? "Waaaaah!" *POUT* It is often accompanied by the stomping of rhetorical feet and tearing of hair. It mostly looks like highly articulate toddlers throwing a tantrum because the world isn't treating them and their pet interests as the center of the universe.
2) How can anyone believe that XXXXX is worthy of their attention and dollars? XXXXX is immoral and anti-intellectual or just plain bad. The people who read/write it are dupes/exploiters or simply uncultured. If people really understood the underlying dynamic of XXXXX they'd realize that and come over and read YYYYY which is the one true way. It mostly looks like even more articulate toddlers throwing a tantrum because the world isn't treating them and their pet interests as the center of the universe.
There's a whole bunch more, and the whole thing is thoughtful, well-reasoned, and delivered with a very entertaining 2-by-4. Go read.
