Tom,

It's highly unlikely that bumps or even potholes are going to cause 1/4" (6mm) thick dropouts to get misaligned. Most likely they came that way from the factory. I've found very few frames with properly aligned dropouts, even from some of the most prestigious marques.

The fork and front axle form a triangle which is an extremely strong shape. The rear "triangle" is composed of multiple triangles.

Dropout alignment unless they are really far out has more effect on wheel bearings and axles than handling. Misaligned dropouts especially in the rear can result in bent or broken rear axles and premature bearing wear over time.
