The homeowner's association in Snowhill meets every third Tuesday at 10:00 am over brunch to discuss matters of the neighborhood. This group is mostly run by nonworking mothers who are available at this time of day. They decide this year that the neighborhood will participate in the annual Christmas parades, not taking into account the needs or religious practices of other members of the community. When neighbors resist participating they are called unneighborly and accused of not supporting the children. What discrimination theory explains the perpetuation of prejudice towards those who chose not to participate in the parade?
