My Dad makes this amazing scallops in a white sauce dish that he served for my sister's birthday one year. I ate the whole thing and sopped up all the sauce with bread and ate that too. I found out later that there was a LOT of garlic in the sauce and spent the next hour curled up on the bathroom floor.
I sometimes write things that get pretty dark. I also write things that are cute and sweet. But if someone told me what I should be writing, I would probably lose my shit. And then write more of what they didn't like out of pure spite. Write what you like. If they don't like it, screw 'em, they can find something else to read, but no one has the right to tell you what to write...or what not to write.
