People could easily argue that slavery would not contradicting the constitution because the domestic tranquility and liberty were followed. People would think domestic tranquility or peace at home was achieved, because slaves did their jobs and were not treated that harshly. But, this is clearly a false statement, due to the fact that they were hit, slapped and pushed around like material. Slaves also would at points try to rebel which would again get them hit or hurt in some other way, so therefor that peacefulness at home will never be achieved when slavery is around. People could also argue liberty was followed because slaves didn’t count as citizens, or really people, but the reality of that is thinking people are unequal still shows racism there if, these people of the certain skin can not be considered citizens. The liberty factor was not achieved because giving the blessing of liberty was not given to all men if a great sum of the population(slaves) were not given liberty. That means that blessing of liberty was not followed showing how slavery could not, not be contradicting the constitution.
