The fact that what we believe about marriage - that it should be between a man and a woman - and that we're pro-life, somehow that becomes radical? Why is that? It's because our culture has changed. But the truth is, culture may change, people change, but the Word of God never changes, and that's what we rest our belief system on.
The message that President Obama delivered in his speech at Notre Dame was: morality is immoral. Pro-life is the extremist position, not a moral position. Yet we should compromise and work to reduce abortions. Where's the compromise between life and death - and why work to reduce the number of them occurring if there's nothing wrong with them?
