I think of the genre thing like music.
Romance is like mainstream, Top 40 pop music. Some people will grumble and say they hate Top 40, but obviously, some people must love it, or it wouldn't be Top 40! It wouldn't be on the radio! Some people may dislike most of it, but will admit to liking a few select songs (stories).
Then you have drama, which is more like rock music. A little darker, a little edgier than pop, but still popular, still on the radio, just a different station. Sometimes you get a crossover, a rock song on the pop station, just like some dramas have subplots of romance, or vice versa.
Suspense is maybe like rap/hip-hop. It's not for everyone, but it does have its fans and a place on the radio and in the mainstream. Sometimes it, too, crosses over with rock (drama) or pop (romance).
Slash could be like country music, the most divisive genre. Like country, you either love it or you hate it. Some people live by slash, where that's all they read/write, and some people wouldn't go near it. Sometimes you get a country song or artist that goes mainstream pop, just like some slash stories are so well-written that they convert people who normally wouldn't read slash.
And then you have sci-fi and fantasy, which are like the underground, indy music, not in the mainstream. There's a lot of creativity and originality going on in these genres, yet for whatever reason, they're not as popular. Dedicated fans of these might look down on the mainstream, yet wish more people liked their genres.
You shouldn't let anyone else's opinions dictate what kind of music you like or make you feel bad for listening to a certain type, and the same is true for fanfic. Be yourself, read/write what you like, and if you have a different opinion, stand up for yourself and express it! That's the whole point of a discussion board! That's why this thread is called "the romantic DEBATE" - I think Mare was hoping we'd have ALL sides in here sharing their viewpoints on the topic.
