No. Parseltongue has nothing to do with the dark side, and neither does the possible piece of Voldemort's soul inside Harry. You're confusing two different things. I'm not trying to argue that he isn't a Horcrux, I'm trying to argue that the dark side is an authentic part of Harry and was not a result of the Horcrux.
Harry has some Voldemort powers. None of those are from the dark side of Harry, though. Nothing about Harry's dark side is Voldemorty except that Harry arbitrarily labeled it dark.
The dark side is ridiculously afraid of death, which we know to be a Voldemort trait. It's also very much separate from Harry.
The next discussion thread is here.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 84. The previous thread has passed 500 comments. Comment in the 14th thread until you read chapter 84.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)
The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system. Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14.
As a reminder, it’s often useful to start your comment by indicating which chapter you are commenting on.
