People in general, especially young people need to be taught more about what segregation was like. They don't understand how pervasive -- or how dangerous -- segregation was.

Young people think broadly about voting rights or economic rights but don't understand how individuals were affected by voting rights. The right to vote was to get people out of office who would bring on segregation.

I don't tell them how dangerous (segregation) was. I tell them how all-consuming it was.

Some people had earlier argued that it took, 10, 20, 30 million years before you got enough heat production to limit that strength.

It puts a human face on this issue. Many people, if they don't have a personal connection to the troops, it's so easy for this to become a discussion that lacks seriousness and urgency. I think it's good to show that there are real people that are being affected.

Well, I will quickly correct the record that they are not anti-war extremists. The majority of people I saw in Crawford were actually veterans' groups.
