I pretty much agree with your take on this.
And integration only goes for so long. There will always be problems. When the Cubans start tearing up Miami and the Mexicans Los Angeles, then we will have the same problems here at home.
However, you lost me with your partisan remark about "leftists" again:
>"We are now seeing the west reassert its leadership and leave the leftist policy of moral equivalence and justification in the dustbin."
It hasn't been the Democrats that let all the Mexicans and Cubans into this country. It was the Republican hacks for political power.
