From The Bench, Causes of Prejudice

This case was primarily about Congress's enforcement powers under the Fourteenth amendment in relation to Title I of the Americans with Disabilities Act:

“Prejudice, we are beginning to understand, rises not from malice or hostile animus alone. It may result as well from insensitivity caused by simple want of careful, rational reflection or from some instinctive mechanism to guard against people who appear to be different in some respects from ourselves.”
