I used to be of a similar mindset, that tools/ideas/practices should possibly be avoided as they can sometimes have a negative affect on people who don't fully comprehend them (such as using design patterns when they're not applicable or where an alternative design would prove to be a better fit). However, I've since come to believe that it's not the ideas that are harmful, it's the people that use them without comprehending them. If this is the case, avoiding a concept that would provide benefit is limiting yourself without any benefit as the people that would misuse them will probably find something else to screw up anyway. Or, to put it more succinctly: "You can write Fortran in any language"
