You stated you don't know a single christian who has a problem with evolution. This poll simply asked whether you accept the theory of evolution. Almost half the country did not accept the theory of evolution.
If you don't like that then look at these:
2010 Gallup poll presented 3 choices
1. God created man pretty much in his present form at one time within the last 10,000 years. (creationism)
2. Man has developed over millions of years from less advanced forms of life, but God guided this process, including man's creation. (Theistic evolution)
3. Man has developed over millions of years from less advanced forms of life. God had no part in this process. (atheistic evolution)
40% of those surveyed agreed with (1). 60% of those who attend church weekly agreed with (1). This largely agrees with a 2004 survey which found similar results.
If 40% of Americans believe in creationism with a young earth and only 46% accept some form of evolution (theistic or atheistic) then it still seems to strongly indicate that a large number of christians reject evolution (not to mention geology). And I would still contend that your experience is unusual. Come to the deep south where I live, and I guarantee you will have a much different experience.
Again I want to know who they polled. If they polled mostly fundamentalist evangelicals, then the results you've posted are probably close to correct. Such, however, are a fairly small minority among all of Christendom.
If they polled Methodists, Presbyterians, Episcopalians, Anglicans, United Church of Christ, Christian Church (Disciples of Christ), most Baptists, most Congregationalists, Quakers, most Lutherans, non denominational, et al, then they wouldn't have found a lot of, if any, "creationists' who deny evolution as you have described them.
The church I attend these days, for instance, has a large population of current and former scientists, engineers, and other such types with Sandia and Los Alamos labs, White Sands, and other similar scientific groups. Most of these folks attend church faithfully every week and are otherwise much involved, but you won't get any of them to say that humans did not evolve from lesser life forms. And I don't think any of them would choose a church that taught significantly different stuff than what they believe.
