You guys (assuming you would have voted no) aren't utopian, just plain naive. You really think discrimination in jobs and accommodations would have ended on their own? When things like that are ingrained into the entire society, they don't change without something of the scale of the Civil Rights Act.
I guess it's also very easy for white men to think about this in completely theoretical terms, isn't it? It's not like you would have been impacted regardless of what transpired without the CRA.
Discrimination was only kept alive in the South because Jim Crow laws made it mandatory. No business that wanted to make a profit would purposefully prohibit a third of the population from being customers. Prohibiting discrimination by private businesses prevented racists from being punished at the marketplace since they were forced to accommodate blacks anyway. It also opened up the slippery slope of intrusion into property rights since it is impossible to tell if one is being discriminatory by making an employment decision absent a mind-reader. Hence, Title VII only encouraged racism by effectively forcing employers to take race into account when making hiring decisions, lest they be accused of discrimination.
But would Jim Crow laws have changed without the CRA?
Stop bringing racism into this you hack. It's all about constitutional rights of states and rights of business.
