Is This Idea Worth Considering?

In a list of proposed amendments to the Constitution Econopundit suggested:

First, disallowance of immigrant participation in US political affairs. This incluces a ban on participation in demonstrations and other public expression of political opinion.

This looks plausible considering the following:

We briefly kicked the immigration issue around at the Houston panel discussion. I recycled my confession, made in the pages of NR 3 yrs ago, that I was an illegal immigrant here myself back in my feckless youth. I noted again what I'd noted in that piece: my conclusion that it is awfully hard to get native Americans to think about immigration. It's a quirk of the national character: we just don't want to take the subject seriously. It goes against the grain somehow. As supporting evidence, I adduced the fact that if you sit down to read up on U.S. immigration policy, you find you are reading books by people who are themselves immigrants (George Borjas, Peter Brimelow), or whose parents were (Michelle Malkin).

It takes time to become assimilated.

On the other hand, that would have prevented a Soviet-trained Jewess from expressing opinions. If we had adopted such regulations a few decades ago, we might be a Third-World nation by now.
