Separate but Equal
There are certain laws throughout history that might make you really wonder what people were thinking. In a 1896 Supreme Court ruling, Plessy vs. Ferguson, the Supreme Court made it legal to segregate public places as long as the treatment was equal. Luckily, to make a long and brutal story short, after many sit-ins and many other peaceful protests, the Civil Rights Act of 1964 prohibited this type of discrimination.
