Is the church more about culture than doctrine?

This is a followup to my previous post: What is Culture? And when I say church I am speaking of the kind of church I am in. One that would be called a fundamentalist Baptist Church. Here's my concern and perhaps I am way off but ...

• I know a seminarian who told me he aspires to be a fundamentalist pastor.
• I believe in the fundamentals of the faith and as one can see from my doctrinal statement that I could easily be called a fundamentalist.
• When I was in seminary school I aspired to be a Baptist pastor.
• What I believe I am seeing in church is that we are more about culture than about a doctrinal position.
• Examples ... discussions at fellowships:
  • What Christian Day school did one attend?
  • What Bible College did one attend? "I went to Pillsbury ... or Northland"
• About the culture of fundamentalism: It seems to revolve around the so-called traditional fundamentalist taboos: Movies, dancing, drinking, cards, et cetera. "behaviors that are expected, rewarded and reinforced by and within a particular group.”
• I sense that our churches have become cultural centers (perhaps I should say "sub-cultural" centers instead of bastions of doctrinal truth. And the church is to be "the pillar and ground of the truth" (1 Timothy 3:15).
• We gather, I fear, wearing the clothing of the fundamentalist club instead of to worship "in spirit and truth" (John 4:24)

Comment: I appreciate your comments. Help me figure this out! What I see as expected:

• Sending one's child to the church's Christian Day School
• A young person enrolling in the approved Bible college
• Being "called to ministry" (want to be rewarded .... express being called!)
• A woman not being a professional.
