Why are Gypsies discriminated against?

Because gypsies migrate all over Europe, they gradually prosper, and sometimes they are forced to engage in stealing, divination and other industries, and they get nothing, so they are associated with diseases and disasters in Europe and are full of hostility. Floating population is the most difficult to manage, and wherever they go, it often leads to social unrest. Gypsies are a people who have never settled down, and European rulers regard them as a plague.
