Heightism Is Natural (?)

There's a scene from Quentin Tarantino's Inglourious Basterds, where the hatred for Jews is equated to the natural fear of rats. Here's the clip:

So what does this have to do with height, or more specifically, short stature?

When a person claims homophobia or racism is 'natural,' they're met with animosity by the majority, as instructed by the media.

"You don't really know why you don't like them; all you know is you find them repulsive."

Convenient.
