Not like certain people living in certain countries, who were, it was said, as human as anyone else; who were said to be sapient beings, worth more than any mere unicorn. But who nonetheless wouldn't be allowed to live in Muggle Britain. On that score, at least, no Muggle had the right to look a wizard in the eye.

Sorry, but I'm not a fan of this part - its not like Britain has immigration policies that ban certain races or religions, so I can only assume EY is arguing in favour of totally unrestricted immigration. But the UK has only a certain amount of room, and there are non-xenophobic economic arguments against unrestricted immigration, e.g. putting too much strain on the NHS. But regardless of the arguments for and against, arguing against immigration is not the same as being indifferent to the lives of everyone who lives in a different country.

I did enjoy the rest of the chapter however. Quirrel's statements about horcruxes were initially surprising - if he is telling the truth, then how is he still alive? If not, then wouldn't he want Harry experimenting with horcruxes in order to turn him to the dark side?

The most plausible possibility is that he wants Harry's help to get the philosopher's stone, and his initial prohibition is reverse psychology. This does help turn Harry against Dumbledoor, but no more than experimenting with horcruxes. Given this, it seems likely that he needs Harry's invisibility cloak / planning ability / human patronus / possibly partial transfiguration to capture the stone.

Still, Quirrel seems to be leaving this too late. Surely it would have been better to move against the stone very soon after the unicorn incident - by which time, Harry's anti-death ideology was very obvious, and emotionally driving. Moving against the stone when comparitivly healthy must increase the chances of success, and if it all goes wrong Quirrel could still have tried to fight his way out...

Unless Quirrel isn't actually as ill as he looks. He seems to have got a lot worse between May 13th and June 3rd.

Edit: I am not arguing that all immigration is bad and everyone should live in neoreactionary ethno-nationalist states. I'm saying that its possible to want to prevent certain people who e.g. have a record of violent criminal behaviour from immigrating to where you live, while still recognising that these people are still human.
