Hostile magic is obviously not the same as Legilmancy

It's also not the same as the sort of LifeAlert wards Quirrell (claims that he) put on Draco, which we know (that Quirrell claimed that) Heh specifically forbade.

Why would Dumbledore care and what would Dumbledore do differently if Dumbledore found out that Quirrell had looked into Hermione's mind?

Well, for one thing, he might look at the Map again. (He suspects Voldemort is trying to influence Hermione's mind; the Defence Prof is caught trying to read Hermione's mind; it doesn't take a genius.)

The fact that the eye contact was specifically mentioned seems important

But it wasn't, though. "The pale blue eyes watched her intently" is not an unambiguous indication of eye contact.

in my mind downvoting should be used for punishing (or expressing disapproval of) immoral things rather than of mistakes

How astonishingly strange. (I don't agree.)

People should probably be more laid back about downvoting.

Yes. People should. (Hint hint.)

This is the first legitimate counterargument that's been made and we're seven layers in, that should tell everyone something.

It tells me that you see far fewer counterarguments as "legitimate" than you should.

I think textual clues outweigh extratextual extrapolation, too. The fact that the eye contact was specifically mentioned seems important, it was probably mentioned for a reason.

As I mention in a comment above, Quirrel's intent gaze is also mentioned in ch. 70, in a situation where we're pretty sure no Legimancy occurred.

Even if I was mostly wrong I would still expect more argumentation and less group ritual display from a website like this.

You refused to accept argument, and you take offense at being corrected as if making you less wrong is a hostile act.

and in my mind downvoting should be used for punishing (or expressing disapproval of) immoral things

Fuck that (ie. I viscerally disapprove of and hold in honest contempt this asserted social norm.) Moralizing gets annoying.

That's not a good thing for people purportedly trying to promote rationality.

ie. Not trying to promote moral purity.

People should probably be more laid back about downvoting.

You're the one getting worked up about it. Really, getting voted down isn't that much of a big deal and even if it was directly challenging it is a tricky social move to pull off.

You guys kind of suck.

So did your... nevermind.
