Just to put it in perspective: The fact that I don't slap doesn't mean I hate it. It's just that I don't. I'm a flatwound addictive and flatwounds and slapping don't really match.
+1 to that
I don't slap/pop or whatever because it just doesn't seem to suit my musical needs/tastes.
Its difficult to hate a technique per say. I'd say its much easier to "hate" the practical application of said technique.
