Outside, It's America

I knew that story must have prompted this. Some of those comments were totally inappropriate, especially since it was such a good story, very elaborate, with an original plot. To say that it doesn't work because Harry would never bottom it's so stupid. I wanted to answer and ask when in canon does it say that Harry would never bottom? And does that apply to Draco only? Is he fine bottoming to Snape? *heads desk*
