The children of Harry and Ginny Potter were considered half-bloods because although Ginny was pure-blood, Harry's mother was Muggle-born. The term was used as an insult from members of fanatical pure-blood families.
The pure-blood wizards and witches featured in the Harry Potter books are almost all supremacists, while there are some of them who do not advocate ancestral superiority; the Potters, Weasleys, and Longbottoms are old pure-blood families, but no known members of these families are sympathetic to supremacist aims.
Coincidentally, Harry Potter, Hermione Granger, and Ron Weasley are each of the three distinct types of wizards; Harry being a half-blood, Hermione being a Muggle-born, and Ron being a pure-blood.
People of this mixed parentage are called half-bloods; magical people with any Muggle ancestry on the one side or the other are half-bloods as well. The most prominent Muggle-born in the Harry Potter series is Hermione Granger, who was born to Muggles of undisclosed names.

Draco Lucius Malfoy (b. 5 June 1980) was a British pure-blood wizard and the only son of Lucius and Narcissa Malfoy (née Black). The son of a Death Eater, Draco was raised to strongly believe in the importance of blood purity. He looked down on half-bloods and Muggle-borns.
Also, James Potter was a pure-blood. One possible theory indicates that the author of the Directory considered the Potters and other "pure-blood" families (such as the Princes, the Crabbes, the Goyles, the Moodys, and the Browns) to have some amount of Muggle ancestry.
Plus, it was implied in Harry Potter and the Goblet of Fire that he was pure-blood which could serve to be another factor in his wealthy background. Despite this, Cedric never managed to inherit the fortune of the Diggory family given his untimely death at the hands of Lord Voldemort.
Ancient and powerful, the House of Black was the largest and oldest pureblood family in Britain. Its motto, Toujours Pur, or "Always Pure," expressed its members' fanaticism for blood purity, which had led them to marry their cousins for several centuries to avoid "tainting" the family's legacy.
Neville is a pure-blood wizard born to Frank and Alice Longbottom, who were prominent Aurors and also members of the Order of the Phoenix during the first war against Lord Voldemort.
Molly Weasley (née Prewett) (b. 30 October 1949 or 1950) was an English pure-blood witch and matriarch of the Weasley family after marrying Arthur Weasley. She was born into the Prewett family and was sister to Fabian and Gideon Prewett, members of the original Order of the Phoenix.

If you count Sirius's fortune, rounded up to 200,000 galleons, that is 243038 galleons or 1.7 million dollars for Harry. Now for the Malfoys. They had about 321,000,000 galleons, about 2.2 billion dollars, and 1.6 billion pounds.
J.K. Rowling says Draco doesn't have a patronus because he never learned the spell but I think it's because he doesn't have any powerful happy memories to use.
The Malfoys are related to the Black family through Narcissa (a first cousin of Sirius Black, Harry's godfather), which makes Draco a nephew of both Bellatrix Lestrange and Andromeda Tonks.
Despite being a pure-blood, he didn't believe that he was superior to other witches, wizards and Muggles. He had a lot going for him and his well-placed morals were even more impressive if you think about the start that he had in life. Sirius came from a family of pure-blood fanatics.
When Muggle-born witches and wizards reached the age of eleven in the British wizarding community, their Hogwarts acceptance letters were delivered in person by a member of the staff, instead of by owl post (the usual postal system for wizards and witches).
Pure-blood elitism. The most extreme of the pure-blood supremacists sought to purge the world of those they consider "impure". They often tolerated half-bloods out of necessity (though still disdained them), but Muggle-borns were persecuted and Muggles were viewed as nothing more than animals.
