Not ALL mainstream denominations are a part of the National Association of Evangelicals, which is what the article is referring to. Agreed, many church bodies do consider themselves evangelical, but the distinction should be made between being evangelical and part of the NAE.
Examples: I belong to an Evangelical Lutheran Church of America (ELCA), yet that body is not a member of the NAE. You said you attend a Methodist Church. One of the more common Methodist bodies is United Methodist and they do not belong to the NAE, though one might argue they consider themselves evangelical.
Most mainstream religion in America, I would argue, is of the Liberal Christian philosphy. A citation from
Wikipedia:
Liberal Christianity, sometimes called liberal theology, is an umbrella term covering diverse, philosophically-informed religious movements and moods within late 18th, 19th and 20th century Christianity. The word "liberal" in liberal Christianity does not refer to a leftist political agenda or set of beliefs, but rather to the freedom of dialectic process associated with continental philosophy and other philosophical and religious paradigms developed during the Age of Enlightenment.
As you'll see from the link below the article referenced group, the NAE, IS the exact same group you are saying we should not be concerned with. Active members of the the NAE include James Dobson and Franklin Graham. The recently resigned head was Ted Haggard.
I imagine we are on the same page, but I want to be clear that the NAE does NOT speak for all Protestants.
