I agree. But few others do. The conventional wisdom seems to be, keep that idea (e.g., racism) in the shadows; as long as we don't see it, it doesn't exit.
Fringe ideas breed in the shadows. They thrive there. They, like vampires, can't live in the light.
Unfortunately, we live in a head-in-the-sand world. And most wouldn't notice a loss of freedom and/or speech anyway.
I know. Sad.
