Protestants are divided into other categories 
(See: www.religioustolerance.org/chr_divi.htm)
   (there are many different ways of categorizing Christians, but this is one
of the more common ones.)

*Conservative wing: (e.g. Southern Baptists and Assemblies of God members).
They firmly believe in historical Christian doctrines, such as: 
 -The inerrancy of the Bible (except for a few copying errors).
 -The Bible not only contains the Word of God, it is the Word of God; God 
  inspired the individual authors to prevent them from error.
 -The virgin conception of Jesus.
 - Creation science: that the universe was created by God less than 10,000
years ago.
...

  They emphasize God as a Lawgiver, Father, Judge, Creator & Redeemer.
  They take a literal interpretation of the Bible.
  Their social views tend to be conservite (e.g. pro-life)
  
 The Princeton Religion Research Center (PRRC www.prrc.com) says:
"Religious conservatives are sometimes viewed negatively as overly strict on
moral issues, close-minded, intolerant of other religious views, fanatical
about their beliefs, too harsh, and placing too much emphasis on guilt or sin,
 too concerned about their own salvation, and too rigid and simplistic.

* Liberal wing: (e.g. United Church of Christ). They see major parts of the
Bible as reflecting God's will. But they generally reject other portions of the
Bible as being no longer valid: 
 - They see such stories as the Genesis creation sequence, the virgin
   conception of Jesus,Ê and world-wide Noahic flood, etc. as myths: 
 -They regard the Bible as errant, having been written by individuals
  without the direct inspiration of God, whose motivation was to promote
  their own theological and spiritual beliefs.
...

 They emphasize God as a Parent, Lover, Healer & Liberator.
 They view the Bible as Some literal, some symbolic; some as simple propaganda
  which should be ignored.
 Their social views tend to be liberal (e.g. pro-choice)
 
The Princeton Religion Research Center (PRRC) says:
"Liberals are sometimes viewed as substituting social concerns for the true
 Gospel, too compromising with the world, morally loose, having a shallow
  knowledge of the Bible and too much influenced by secular humanism." 

*  Mainline wing: (e.g. Presbyterians and Methodists). As the name implies,
these are faith groups whose beliefs, priorities and policies lie between the
conservatives and liberals: 
 - They look upon the Bible as containing the Word of God but do not
necessarily view all passages being the inerrant word of God.Ê

 - They are divided about belief in the origins of life and the universe.

In a Apr. 4, 2004 NY Times article "The Return of the Warrior Jesus", David Kirkpatrick describes the popularity of the popular "Left Behind" series of apocalyptic thrillers by Tim LaHaye and Jerry B. Jenkins.
He says: "The fight for a manly Jesus has been long-running. At the beginning of the 20tgh century, some Christian critics railed against what they called "bearded lady" portraits of Jesus of the Victorian Era. But the battle over the manliness of Jesus had settled down by the middle of the 20th century, when the relatively liberal, mainline Protestant denominations were at their apex."

"In a survey of students at 16 evangelical colleges and seminaries, "over 50% of those surveyed, for example, said the Bible should not be taken literally in matters of science and history. Over 30% said that those who never had an opportunity to hear of Jesus Christ could nevertheless go to heaven."
