I don't think there ever has been a sensible fight other than the fight against ignorance and arrogance and the fight that is specific in it's subject matter. Category Theory and other abstract fields I would think get resistance at the time of introduction; concrete mathematics get resistance much after the fact for its specificity. In both cases one should be careful to either put on a pedestal or throw down the drain.
