To head off a whole bunch if off-the-main-point criticism, let me refine
this sentence to: "Some day all physics teachers will agree on whether
forces _can_ cause accelerations." (i.e. whether the F_net in F = ma
_causes_ the (non-zero) a in F = ma.)  I already understand that when the
sum of the forces on an object is zero that the constituent forces aren't
causing any acceleration (because there is none).
