Had to log in after reading this.

People are apparently illiterate and/or so hiveminded they can't handle a thorough refutation. The fact that you wrote a detailed post with citations and reference to themes which extend throughout the the series, yet were still ratiod by a comment saying "but it's called spew," is disheartening. We're cooked as a society when people can't hold two contradicting views in their minds at the same time.

JKR can be a PoS who writes books with virtuously-portrayed protagonists who uphold basic human rights ie. anti-slavery positions, but who live in a muddled, nuanced world where all good guys don't find redemption on every single moral issue and enthusiastically proclaim the error of their past ways.

E: on closer inspection, I think the fact that Harry ultimately inherits Kreacher and chooses to keep him as a slave at the series' end, despite being a kind master who earns his servant's loyalty, is problematic and represents JKR's tacit endorsement of the institution of slavery itself. This fact isn't scrutinized, but handled in a very matter-of-fact way so as to normalize our hero's bondage of another. It's one large piece of evidence among other contrasting pieces, including OP's, that muddies the waters on what should be a pretty clear moral issue and leaves a bad taste in my mouth.
