> Magpie:
<snip> I thought his hesitation about whether or not Lily could be a
Slytherin was a small boy knowing it was a problem but hoping it
didn't apply to Lily. <snip>

Carol responds:
But he didn't hesitate about whether Lily could be a Slytherin. His
saying to her on the Hogwarts Express that she'd better be in
Slytherin (where he hopes and expects to be Sorted) is what starts the
incident with James and Sirius. No hesitation at all. He mistakenly
believes that she can be Sorted there. After all, he also mistakenly
believes that it's the House for "brains" (which suggests that he's
never heard of Ravenclaw).

Carol, who agrees that we can't know what he was taught but sees no
evidence that his clear prejudice against Muggles extends to
Muggleborns at this early point in his life
