America is or should be about inclusion. Immigrants like muslims don't and can't fit the white European mold that prevailed in this country 50 years ago.

Being out of the mainstream is entirely consistent with the way Donald Trump is approaching his presidency.

The First Amendment to the Constitution says government can't establish a religion, but neither can it limit the exercise of religion. And that's the issue here. What does it mean to be free to exercise your religion? It's not about what you can believe. It's whether you can act on those beliefs.

Many immigrant groups have faced hostility. The Irish did in their time. Jews did. Italians did - and now, Muslim immigrants.

As Cuba's leader, Castro answered to no one and allowed no challenge to his authority.

Hispanics are the fastest-growing evangelical group in the country right now, an important constituency. But Trump's views, especially his views on immigration, did not exactly go over well with this faith constituency. Rev. Rodriguez told me that Trump's invitation created something of a stir in his world.

In some states, it is illegal to turn down a same-sex couple when you're placing children for adoption. That's discrimination. But in the Catholic church, the sacrament of marriage is defined officially as the union of a man and a woman. So a Catholic adoption agency is torn between its faith doctrine and what it sees as a faith obligation to help orphans.
