determinism

I don't understand how anyone could arrive at a conclusion that true randomness exists anywhere. Or rather, I do understand it, but I think it is rather stupid. I guess a common misconception is that QM proves determinism is impossible, but that's not true at all. The only thing it proves is that some things are beyond our ability to measure; the underlying mechanism can still be fully pre-determined (in fact, this is the only logically consistent position).

Actually, the "underlying mechanism" is what is semi-probabilistic, and there's no real logical inconsistencies. Indeed Bell's Inequality refutes the empirical existence of any such hidden structure:
