Yes, this is true. In brown vs board of education of Topeka, the case got a legal victory due to the fact that it wasn't separate but equal, as the girl had to walk 20 blocks - a few miles - to get to her school, as she attends a black school. white people were able to get to schools near them, which is totally unfair. so the supreme court said 'separate but equal' is unconstitutional.
Enlightenment principles called for freedom of thoughts,individualism, liberty, skepticism and reason,especially skepticism to traditional religious views.
The period after the ww1 broke out, saw an increased wave of revolutions,across the century, agitating for freedom and liberty, as well as the fall of collectivization or communism to the rise of capitalism, and increased secularization of society. enlightenment thoughts were therefore highly successful.
