is the word 'cracker' racist?

[Devout Pessimist]

Lol, so if calling a white person "cracker" isn't racist....what would a person have to do to be racist?

The logic in this thread is really out there.

Suey Park is extremely racist, but claims she is not racist because according to her you can't be racist against white people.

Here is a typical conversation on her twitter feed.
