Why thank you so much for educating us on the proper definition of bias, craigsub. Because as ignorant as we all are, we had absolutely no idea.

Here are a few more definitions (from the Oxford Dictionary).
Bias: Prejudice in favor of or against one thing, person or group compared with another, usually in a way considered to be unfair
- A concentration on or interest in one particular area or subject

Given those definitions, I find the use of "everyone has biases" to be quite appropriate.
