"I don't know..." Katie said slowly. "But if he thinks Muggles are dirty, how can that not mean that people related to Muggles have that dirtiness in them? That they're lesser just by virtue of that. If you follow their logic, I mean." She shrugged and then sighed. "Of course he has a right to think what he wants. That doesn't mean it's right, or that I agree with it. I mean, someone has the right to think that all quidditch players are idiots, or all Gryffindors are overly emotional... that doesn't make it true. Generalizations are never a good thing." She sighed again and then shook her head. "It's alright, we can just forget about it. I don't want to ruin the party okay?" Besides, she had a feeling she could argue this point all night and never get anywhere.
