Rookas,
Don't take this wrong - it isn't meant to be anything more than an honest response to your question.
If you want to be a professional, if you want to earn the respect of other pros, and if you want to improve as a musician, you must learn to respect the music.
This means that just as you would expect a classical player to respect jazz, you must do the same in return. A true pro will put in the work necessary to learn to play a style of music correctly, and will try to have a broad range of styles he can pull from. If he finds that a certain style is just not something he can master, he will respect it by staying away from it.
Mastering at least some classical piano will benefit you in other areas of performance. But you must give it the respect it deserves. For instance, you mentioned stride. Have you really put the work into learning to play stride piano accurately, or are you simply referring to left hand octave/chords as stride? If you are going to play stride piano, you must respect it enough to learn it play it correct to style. Only after you have mastered the proper basics of a style correctly can you afford to add your own twists to it or 'let your fingers think for you'.
Again, this is all meant constructively, not as a slam. But 'just going off' is the work of an amateur who is impressed with where he is and is satisfied with that, not the work of a pro. So to answer your last question, it is not the music you must detach yourself from. It is your view of yourself and your playing skills you must face.
Get serious about broadening your range as a musician, and get serious about the music. If you do, you will improve in every style you have at your disposal. If you don't, you will stagnate.
