It requires skill and talent to use electronic equipment to create good quality music. There are hundreds of thousands of people who try and fail (just look at YouTube) so it can't be that easy. Certainly not as easy as you are making out.
It's clear to me that you haven't ever attempted to create a mix, let alone tried to use a deck and mixer, and are just assuming that you stand on stage and hit the play button. Making a quality track takes hundreds of hours of painstaking attention to detail, just as a symphony does. A deck and mixer is no different to an electric guitar and effects pedal... it's still an instrument, except that a deck and mixer is way more complicated to use (and I can say this for certain as I play multiple instruments, and have used numerous bits of electronic kit).
I really don't understand why you need to hate on other music. I don't like the majority of modern pop, but I don't spend my time hating on it. My friends don't hate on me because one minute i'll be playing metal, then classical, then spiritual, then house, etc. Stop acting like a little kid and tolerate the things that you don't like like an adult.
