What is the most shocking Jim crow law?

One of the most shocking Jim Crow laws was the "One Drop Rule," which stated that any person with even a single drop of African ancestry was considered Black and subject to the same discriminatory laws. This law effectively erased the identities of many individuals of mixed race and reinforced the rigid racial segregation of the era. Additionally, it perpetuated the myth of racial purity and justified widespread discrimination and violence against Black individuals. The One Drop Rule exemplified the extreme lengths to which Jim Crow laws went in enforcing racial hierarchy and oppression.
