Why is it seem like the vast majority of "news" that secular media seems to cover in regards to the Church (Christianity) seems to revolve are sex scandals and queers? Is that really the extent of the Church's relevancy in the 21st Century? Do people realize that the Church is on the forefront when it comes to caring for sick and the homeless? Why does the media seem to shy away from covering stories in which people's lives improved because of what the Church provided? Which leads to another question, is the term "secular" in America often a code word for a "religion", one who's tenets are built on rationalism (ie. worship of the self), and sexual "freedom"? In other words, is "secularism" in America another name for a movement which opposes everything that Jesus stands for and is indeed anti-Christian? Is the media actively trying to promote its "values"?
Human interest stories don't generally make it to the first page. Scandals do. I think scandals involving religious figures are even more interesting just by virtue of the hypocracy involved.
You're right that stories about the church or churches helping people don't get much coverage, but then again when was the last time you read or heard anything about the Peace Corps? The only time you hear about the Red Cross is either as a footnote during the coverage of some disaster, or when one of their officials got caught with his hand in the till (scandal again).
I really don't think this is a case of anti-religious sentiment.
And btw if you're worried about a lack of positive portrayals of Christianity in the media ya know you could start by working on setting a positive example yourself right here.
