The whole thing about people being defensive is interesting. I love techno, but anyone who has learned other styles of music recognizes the repetitiveness and quirks of a lot of techno and some other electronic genres.
They do a great job with changing their timbre and tones but often ignore a bunch of other factors that make music interesting. Whether that is the rarity of time signatures other than 4/4, the way certain rhythms are locked into certain genres, the choices of keys used, the limited or missing chords, etc.. at some point you start hearing two electronic songs that sound totally different at a superficial level and you realize they're incredibly derivative of each other.
