This is what happens when we allow (encourage) huge numbers of illegals, and when we water down the basic educational requirements for attaining citizenship. We get a big segment of society who do not understand that when they live in the United States of America they agree to live under United States of America law. Instead, we now have a subset (or several different subsets) of society who are not "Americans," who have no desire or intention to be come "Americans," who are just living in "America" to take what they can from the gravy train and who think they can continue to follow the same customs they followed back in wherever it is they came from.
We need to get back to teaching citizenship before we award citizenship, and we need to start making some basic understanding that we operate under OUR legal system here a requirement for any kind of permanent residency status.
And, of course, we need to hire enough buses for about 12 million illegals, but that's another story ...
