One of the problems of involving the political system in addressing social problems is that it is not a very precise instrument. Knowles' statement is an example. There is a difference between tolerance and celebrating diversity. The one is passive, the other active. We can't compel either.
Tolerance is an attitude.
We can pass laws requiring the appearance of tolerance in behavior, but we can't require people to be tolerant in their hearts. Look, we can't even agree on what should be tolerated, let alone celebrated. But many of them, the hard core, live on the street because they drink. Their lives are difficult in many ways, one of them being that they are attacked by groups of young, white men and boys. They shouldn't be attacked.
