It really depends on what you mean when you say force. Like so many concepts that we can all agree on in Newtonian physics, the concept of force has to be refined when you go to relativistic physics. In Newtonian physics, objects move in straight lines unless acted upon by a force. Those forces include gravity. In general relativity, objects move on geodesics (the generalization of a straight line) unless acted upon by a non-gravitational force. So in that sense, gravity just redefines "straight line" and doesn't behave like a Newtonian force.

However, Newtonian forces act in flat (Cartesian) space and an independent time dimension, while gravity in general relativity is described by the curvature of space-time. In this sense, the fact that the geodesic isn't a straight line is due to gravity. So gravity is deviating straight lines.

I haven't done a poll, but gravity is still taught as a force in most textbooks, and I suspect that most physicists would say that it is a force, but seems to be very unlike the other forces in having its properties bound up in space-time.
