DOGMA: a political belief one is unreasonably committed to, such as the notion that freedom is good and slavery is bad.
BIAS: predeliction for a particular dogma. For example, the feminist bias is that women are equal to men and the male chauvinist bias is that women are inferior. The unbiased view is that the truth lies somewhere in between.
