This profound quote from www.thewordfortoday.com.au/blog-calendar-6683 :
Prejudice is the product of a lazy mind. It's contempt, prior to investigation. Your first impression of someone is incomplete and often inaccurate. Don't assume your intuition is always right. Don't make lasting decisions based on limited insights. Your success in life will be adversely affected by prejudice, fear and any form of discrimination you allow to colour your thinking. Jesus never determined a person's worth based on their race, gender, financial status or appearance.
(The word ignorance also comes to mind).
