For aerodynamic air bearings this is certainly a true statement, but I do not know that it is a primary concern for plain bearings with sufficient oil pressure. Pressure in a fluid is applied evenly, more or less, to the surfaces.
Also I can guarantee that for a given torque level, there are a lot greater forces at work and stress at higher rpms.
