There is a considerable difference between being influenced by Calvinist thought and being "Calvinist".

Calvinism (in my opinion) involves a strict traditional hierarchial denominational structure, an emphasis on predestination, and (to put it bluntly) a total quenching of the holy spirit.

An example of such would be the reformed Presbyterian church.

Perhaps the point where we disagree is not the definition of Calvinism but the definition of evangelicalism.

Over time the word "evangelical" has been applied to a variety of different movements that had little in common with one another other than the name.

My particular interpretation of the word is as it is explained in the excerpt below. Particularly in the highlighted section:

"The modern usage (of the word Evangelicalism) usually connotes the religious movements and denominations which sprung forth from a series of revivals that swept the North Atlantic Anglo-American world in the eighteenth and early nineteenth centuries. Key figures associated with these revivals included the itinerant English evangelist George Whitefield (1715-1770); the founder of Methodism John Wesley (1703-1791) ; and, the American philosopher and theologian, Jonathan Edwards (1703-1758).

These revivals were particularly responsible for the rise of the Baptists and Methodists from obscure sects to their traditional position as America's two largest Protestant denominational families.

Indeed, by the 1820s evangelical Protestantism was by far the dominant expression of Christianity in the United States. The concept of evangelism and the revival-codified, streamlined, and routinized by evangelists like Charles G. Finney (1792-1875)-became "revivalism" as evangelicals set out to convert the nation. By the decades prior to the War Between the States, a largely-evangelical "Benevolent Empire" (in historian Martin Marty's words) was actively attempting to reshape American society through such reforms as temperance, the early women's movement, various benevolent and betterment societies, and-most controversial of all-the abolition movement. After the war, the changes in American society wrought by such powerful forces as urbanization and industrialization, along with new intellectual and theological developments began to diminish the power of evangelicalism within American culture. Likewise, evangelical cultural hegemony was diminished in pure numeric terms with the influx of millions of non-Protestant immigrants in the latter 19th and early 20th-centuries. Nonetheless, evangelical Protestantism remained a powerful presence within American culture (as evidenced by the success of evangelists like Dwight L. Moody and Billy Sunday). Going into the 20th-century evangelicalism still held the status of an American "folk religion" in many sectors of the United States-particularly the South.

As you say certain of the influences that formed evangelicalism were Calvinist, Jonathan Edwards was a puritan for example. But the systhesis that came about is far from typical Calvinism.

So to reaffirm and clarify what I said before.

Despite its varied roots which do include some Calvinist influence, Evangelicalism, in its modern sense, is not, and has never been "Calvinist".
