I believe that we as a country have never come to terms with our racist past—not that racism is in the past. It is alive and well in many of the sick parts of our society. I fully agree with you that much of what the Republican Party stands for can be described as slavery. To be enslaved is to be held in bondage. The plight of black and brown school children forced to attend substandard public schools is a form of bondage because most of their parents cannot afford to send them to better schools.
The plight of undocumented agricultural workers who are denied a path to citizenship is a form of bondage because they have no rights without citizenship, even after having worked here for decades.
The plight of women forced to birth unwanted children is a form of unwilling bondage because the woman is now forced to carry the burden of caring for a child, often without the economic resources to do so.
The future plight of LGBTQ if Republicans are able to resurrect sodomy laws and overturn same-sex marriage and other civil rights will become a form of bondage as LGBTQ will either have to flee for their lives from red states or face living in secret and fearing being caught.
The image of slavery should no longer be the black person in shackles. The Republican Party has found ways to metaphorically shackle black and brown people, women, and LGBTQ.
