I would not call her a bigot. Its more that she believes what she has been taught, and is honest enough to be honest about it.
In the description of bigot...it mentions "hatred" and "intollerance".....from what I can see she has not mentioned or acted with either.
There are many subjects that people have formed an opinion of, because they believe in what they have been taught or what they have read, from flying saucers, evolution or whether white bread is better than brown bread.
Whether she learnt it from the bible, or read it in a dietry book she like most of us form an opinion and believe it, and we state our belief if we are asked, just like she did.
It doesnt make her a bigot.
