I never said that your DJ friends are the best in the world, and I certainly wouldn't claim that I am the best guitarist in the world. I can state with absolute certainty that with very minimal time, I can do a better job as a DJ than any DJ can do as a guitarist. If you claim otherwise, I suggest that you ask them how they think that they would fare.What kind of nonsense is this, turbo. My 'best DJ friends', are not the best DJs in the world - and I never claimed they were. Your who can perform on whose equipment means jack squat. Unless YOU can perform BETTER than the best DJs in the world (as you claimed), you're talking out of your tooshey. You said, "I can play better than any of those DJs if I wanted to". The answer is NO YOU CANT. So instead of admitting it and respecting the work of fellow musicians, you cry oh they arent musicians. They just steal peoples music. How pathetic, turbo. Do you hear DJs saying, oh Jazz artists just bastardize classical music with all that random noise no one wants to hear. They work the classical artists out of a job! No, at least DJs show some respect. Why can't you do the same?
DJs are not musicians. To be a musician, you have to actually learn how to play an instrument, master it, and learn how to apply that knowledge to work with others and make a finished product. It is not enough to know how to make a few chords or to play a lead or two - if you are to perform live and be good at it, you have to have a large repertoire of moves and be able to execute them seamlessly.
I see that you have gone back to the position that you previously said you didn't really mean (bolded) that shows you don't really have a clue about performing arts. Playing improvisational music is demanding, and it is very apparent that you have never done so, nor do you have an informed viewpoint on it. Jazz is not a perversion of classical music, any more than rock or blues are. Music is evolutionary, and has to be viewed as such. You are a consumer, not a producer, and have a (conveniently) narrow perspective.
BTW, I know people who play classical music, including a classmate from college who spent his summers touring Europe and sitting in as a guest violinist in some of the finest orchestras. He didn't think jazz was noise, and he used to sit in with me and my friends when we played blues/rock/whatever. Your very narrow definitions of good/bad amount to nothing more than straw-man arguments, in which you can paint something in a negative light and then diss it. I played classical music, traditional music, marches, etc in HS, and liked all of it. The most fun I had in that period was playing tight, but improvisational music along the lines of the Tijuana Brass - another trumpet player, a baritone and tuba player wanted to do some ensemble work, and we worked up a nice set of tunes.
