Dear Beanman,
when you get to highschool you will hopefully learn some more convincing techniques in argumentation which will save you from developing a reputation as an obnoxious person.
To prove that an artist is worthless (as opposed to just saying that he is without evidence), you have to point out deficiencies in their BEST works, not their WORST works (e.g. alla turca). So go and borrow cds of his best works (e.g. the requiem, some late concertos (e.g. piano concertos 20, 21, 22, 23, 24,25, clarinet concerto), Don Giovani, Symphonies 39, 40, 41, C minor piano sonata+fantasy) and point out their musical deficiencies in a rational way.
You call him feelingless, but that's not what I hear in works like these.
You complain about the joke aspect of Mozart, but Haydn and Beethoven do lots of musical jokes too.
I wish you well in this phase in your personal development.
