Will Ethnic Diversity Destroy America? part 2

Here are the next two points given in a speech entitled "I have a plan to destroy America," by Richard D. Lamm, former Colorado governor (see the first in this series for background).
3. We can make the United States a "Hispanic Quebec" without much effort. The key is to celebrate diversity rather than unity. As Benjamin Schwarz said in the Atlantic Monthly recently, "The apparent success of our own multiethnic and multicultural experiment might have been achieved, not by tolerance, but by hegemony. Without the dominance that once dictated ethnocentrically, and what it meant to be an American, we are left with only tolerance and pluralism to hold us together." I would encourage all immigrants to keep their own language and culture. I would replace the melting pot metaphor with a salad bowl metaphor. It is important to insure that we have various cultural sub-groups living in America reinforcing their differences, rather than Americans emphasizing their similarities.
4. Having done all this, I would make our fastest-growing demographic group the least educated – I would add a second underclass, unassimilated, undereducated and antagonistic to our population. I would have this second underclass have a 50 percent dropout rate from school.
RASMUSSEN COMMENTS:
a.  I agree with some of these points. Mere tolerance is a poor basis for survival. Engagement in relationship, working through issues, is a much better option, though more difficult. Tolerance, while a positive characteristic, can be taken to an extreme where people are afraid to stand up for what they believe in. Such hyper-tolerance is just as bad as intolerance.
b. With his repetition of a "rather than" dichotomy, Lamm casts diversity against unity as an either-or dynamic. By inference if not actuality, he says that we must choose either diversity or unity, and the latter is clearly better. My belief is that unity is meaningless (in fact, nonexistent) without diversity. We can't have a mosaic without different shapes and colors of glass. We can't have an orchestra without violins, cellos and trumpets in collaboration. We wouldn't have a body except for its different complimentary parts. So what we need in American is different groupings freely and joyously celebrating their cultures while at the same time gladly enjoying and contributing to their citizenship as Americans.
c. Lamm's fourth point is enigmatic. Who is he indicting here, the poor Hispanic migrant worker who refuses to get an education? If anyone stands to blame for the chronically poor (whether the inner city black youth or the Hispanic poor), it is the upper-middle and upper class who perpetuate poverty by enjoying privilege without concern for the poor. This point is a really cheap shot, woefully oversimplifying a very complex situation with a fear-mongering, blame-spewing venom that adds nothing toward a solution. It is the finger-pointing judgmentalism of one who sits in a seat of privilege and pretends he is not a part of the problem. If this attitude prevails, ethnic diversity will destroy America--not because of the diversity but because of the ethnic-pride of those who sit self-righteously in their comfortable lifestyle, accusing newcomers of creating all the problems.
