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

Administration officials, in fact, have repeatedly condemned ISIS for its treatment of religious minorities, including Christians. But a bipartisan resolution now moving through Congress calls on the administration to go further and say ISIS is guilty of genocide.

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

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.

ISIS goes after any group that deviates from its extreme ideology, dissident Muslims, for example, or the Yazidis who practice an ancient religion distinct from both Islam and Christianity.

One of Donald Trump's criticisms of President Barack Obama and of Hillary Clinton was that they seemed reluctant to use the words radical Islam. It was not just semantics. Trump said it's important to name the enemy idea and then attack it. Consider the Cold War. The U.S. and its allies waged a kind of propaganda war against the communist idea using radio broadcasts and other tools. Trump has said he'd do the same against Islamic extremism.

A similar move is underway in the British Parliament. Earlier this month, more than 30 religious leaders and scholars wrote Secretary of State John Kerry asking for a meeting to discuss what's happening to Christians and other minorities. Nina Shea organized the effort.
