Cite examples from the text to support your claim. From the story " Harry Potter and the chamber of secrets.

The Dursleys' hate everything which is not "normal"; they especially hate Harry and his parents who passed away because of their magical powers and abilities. They are doing their best to hide Harry from people around them because they are ashamed of him and afraid of his powers:

Ever since Harry had come home for the summer holidays, Uncle Vernon had been treating him like a bomb that might go off at any moment, because Harry Potter wasn't a normal boy.

They do not consider him normal and they are trying to eradicate his magical powers by taking away his school books and another magical stuff from him and locking his owl into the cage without letting her out. They cannot stand the fact that Harry is a wizard, especially Harry's aunt, Petunia, who hated her own sister (Harry's mother) because she was a witch:

As a matter of fact, he was as not normal as it is possible to be. Harry Potter was a wizard.

When it comes to Harry, he loves magic and he misses Hogwarts, his friends, his classes, his quidditch trainings, etc. and his greatest wish is to go back to school and escape from the Dursleys', as they cannot understand his world:

He missed Hogwarts so much it was like having a constant stomachache. He missed the castle, with its secret passageways and ghosts, his classes, the mail arriving by owl, eating banquets in the Great Hall, sleeping in his four-poster bed in the tower dormitory, visiting the gamekeeper, Hagrid, in his cabin next to the Forbidden Forest in the grounds, and especially, Quidditch, the most popular sport in the wizarding world.

Harry cannot imagine his life without magic anymore, as it is the heritage he received from his parents and he feels proud because of the fact that he is a wizard.

The difference between the Dursley's perception of magic and Harry's perception of magic is that Harry thinks it's natural, nothing to be afraid of, while the Dursley's hate it and think it is an abnormality.
