I don't think it's blindness, but rather ignorance.
These are the children of parents who sent them to public schools.
It's a little of both, but it wouldn't matter because I don't think anything with these "protestors" of today is really about issues.
What they are is a generation of spoiled wannabe's. More than anything else they're just ticked off that they were born too late to grow up in the sixties. Most have a shallow understanding, if any, of real-world politics and they have the trained seven-minute attention span of children raised on television.
That, and they're there to get chicks.
