He refuses to teach the advanced kind, and expects she can't perform the regular kind in any case (which she tried). Draco couldn't learn regular Patronus because, being a Slytherin, he never made a honest effort.

Harry should be able to help Hermione find a happy thought appropiate for Patronus 1.0, as he did for Draco.

Inability to find a happy thought is not the problem.

Not all happy thoughts work. Harry suggested to Draco a particular happy thought that would work: his father protecting him from human frailty. This is appropriate to protect against a symbol of death, as Harry's father buying him books is not.

So no, Hermione's problem is not that she can't find a happy thought, but that she doesn't know what sort of happy thought she is supposed to find.

Um, it's pretty much established the reason Hermione can't cast an animal Patronus is because she doesn't have faith in an afterlife...

I don't think it was established one way or another what the reason for Hermione was.

The standard Patronus "feels wrong" when Hermione tries to cast it, just as it does to Harry.

Really? Cite? I didn't catch that.

Didn't Harry also swear to keep what he and Draco experiment with secret? This is why he never told her about the magic gene either, unless I am misremembering things.
