You are right. I realise now how disabling parity check endangers the life of every single internet user.

Interesting conclusion you draw there instead of understanding the metaphor, a metaphor which was intended to highlight a logical thinking flaw and your reply shows that you suffer badly from it.

Error detection circuitry increase manufacturing cost and is not something the manufacturers just throws in because they think it is fun.
Disabling such a circuitry, wherever it is used, whenever it reports an error is not so smart and assuming that the error detection circuitry is faulty is a bad assumption.
Each parity bit is protecting its own set of 32 data bits and will trigger an error if any of them (including the parity bit) should have an error.
The chance of the error being in the data bits is therefore 97% and the chance that the parity bit itself is the erroneous one is 3%.
But yeah, go ahead and disable the checking..
