Final answer:
There is no evidence to suggest that the Marine Corps in 1798 took actions to promote racism.
Step-by-step explanation:
The question is based on a false assumption. There is no evidence to suggest that the Marine Corps specifically took actions in 1798 to promote racism. However, it is worth noting that throughout history, the U.S. military as a whole has had a complicated relationship with racism and discrimination. There have been instances of racial segregation and discrimination within the military, but these issues were not limited to the Marine Corps or a specific timeframe.
