Hogwarts gets Owned!

I loved the Harry Potter books when I was little and they're still somewhat entertaining but unfortunately nowhere near the 'WOW' factor that they used to have. There are a number of behaviours which don't make sense, such as the fact that people keep saying that Albus Dumbledore is the greatest headmaster Hogwarts ever had while it's perfectly clear that the school is run terribly.
Here are some adjustments the school should make.

1. Eliminate Slytherine house as an option.

If we know Salazaar Slytherine was a racist murderer then why does he have his own house?
In the second Harry Potter book we discover that Slytherine House's founder built a secret chamber with a monster in it that would kill wizards born in non-wizarding families on command. Once this was established, Slytherine house should have been dissolved. They now know that Slytherine was a racist murderer and yet they continue to prize the values of a racist murderer so much that they keep this house as an option. Why?
That's appalling. Putting a student in Slytherine house to learn racist propaganda off each other has gotta be close to child abuse.

2. Fire Proffessor Trelawney, the Divination teacher.

I don't get why she doesn't get fired when Dumbledore knows full well that she's a fraud. She's teaching all the students bullshit! Dumbledore's meant to be the best headmaster even, yet he deliberately hires a fraud to teach bullshit? What the hell were the other Hogwarts Headmasters doing?
Not only is she indefensible in principle, but she's a sicko. In the third Harry Potter book, she told Harry, who she knew had a dark wizard currently trying to kill him, that he was going to die soon.
That has potential to seriously mess a person up psychologically.
How does she keep her job? How?

3. Expel Peeves the poltergeist.

Filch, the caretaker is constantly trying to have Peeves expelled. Why on God's green earth hasn't he succeeded? What is the argument for keeping him? He doesn't do anything useful! All he does is play dangerous, irresponsible jokes on people. It's hard to tell who's more useless, him or Professor Trelawney.
It's pretty obvious that Peeves is only written into the stories for comic relief, and that the school can't lose him because it would lose it's comic buffoon, that the reader can laugh at. But he has no practical use at Hogwarts.

4. Fire Professor Snape, the Potions Master.

Snape uses WAY too much negative reinforcement in his teaching methods. In book three he actually threatens to poison a struggling, frightened student's pet toad if he doesn't perform at a higher academic level. That is a firing offense in itself.
I'll say this in his favour. You'd DEFINATELY take your schoolwork seriously if your teacher threatened to kill your pet.

5. Fire Professor Hagrid, the Care of Magical Creatures teacher.

Hagrid is an incompetent, bigoted arse-clown.
In book three when Buckbeak the Hippogryff gored Malfoy it WAS his fault. When you're explaining to your class how to not get gored by a wild animal it is absolutely essential to be certain sure all the students are listening. He did not do that.
It's also illegal to cross-breed different types of magical creatures and smuggle dragons into your house. He doesn't learn. He keeps doing this stupid shit.
He's also the most bigoted of all the protagonist characters. He shows that he apparently finds all muggles disgusting when he tells Vernon Dursley 'I'd like to see a great muggle like you stop him', states in book two that the reason the Malfoys aren't worth listening to is that they have 'bad blood' and tells Harry in book four (in relation to Madame Maxime) 'these foriegners, you can't trust any of them.' All of these bigoted statements were in front of young students.
What's more when Hagrid is busy and can't teach, it's pretty clear that his substitute is much more competent, as she doesn't cross-breed dangerous creatures and introduce them to animals that might gore them to death.
We're supposed to hope that Hagrid keeps his job because he's a friend of the Harry, Ron, Hermione and Dumbledore and because everyone who tries to get him fired such as Malfoy and Umbridge do it for stupid, biased, bigoted reasons. I do NOT hope he keeps his job. I believe quite objectively that he is an incompetent boob and that Harry, Ron, Hermione and Dumbledore are recklessly endangering the educations of their fellow students, because they don't want big baby Hagrid to start crying because he lost his job.

6. Fire Filch, the caretaker.

If you hate children it's a bad idea to work in a school. Uh-Duuuuuh!

7. Teach Professor Flitwick, the charms teacher common sense.

Professor Flitwick did a terrible job defending the Philosopher's Stone in the first book. Flitwick charmed keys to fly around, AND LEFT RACING BROOMS RIGHT THERE IN THE ROOM SO THE BURGLERS WOULD HAVE A CHANCE OF CATCHING ONE! Why would you do that? They're BURGLERS! You're meant to keep them AWAY from the stone... IDIOT!

8. Fire Professor Binns, the History of Magic teacher.

He's dead already. He's a ghost. And he was a boring, shit teacher when he was alive. He puts all his students to sleep. Fire him!

9. Fire Dumbledore, the Headmaster.

For making, many, many, many terrible, biased and downright inexplicable staff appointments, and running a school which keeps a house known to be founded by a racist murderer.

Do all these thing and this train-wreck of a school will be on the road to recovery.
