I ran across this meme on social media:

Although slavery was a world-wide phenomena and did not originate with just one race, it was ended in the United States of America and elsewhere by the majority of people who were not slaves. The creator of the meme expects to gloss over any changes that have occurred in the United States since it was founded as though nothing has changed. Specifically, the meme’s author/propagandist mentions that the “discriminatory practices of the past still have ramifications today.”
Slavery, a discriminatory practice, was outlawed in December 1865 by the Thirteenth Amendment to the US Constitution. Certainly after this change that discriminatory practice was eliminated and no longer has ramifications on people after that date.
The Civil Rights Act of 1964, a Federal statute, outlaws discrimination based on race, color, religion, sex, and national origin. The US Attorney General has the obligation to address complaints alleging discrimination, so even if someone attempted to discriminate against someone else based on their race, color, religion, sex or national origin their behavior is against the laws of the United States of America and they are liable for prosecution.
The changes to the discriminatory practices of the past have been instantiated.
Any discriminatory barriers erected in the past have been legally removed and yet some propagandist glosses over them as though we are still stuck in the 1860s.
Every US citizen is an equal partner in our great nation. Some folks attempt to facilitate the mental chains and further the supposed victimization of others to divide our population. They are the ones who failed to remove the barriers, they are only building more.
