t IS meant to be computationally infeasible to find two messages with the same hash.
It is mathematically IMPOSSIBLE to reduce every 32 byte message, to a 16-byte hash and and not have duplicates. If you believe otherwise I have an infinite compression algorithm that you might like to fund development of?
The only ignorance is that on behalf of those that don't understand simple logic--like you apparently.
Examine what is said, not who speaks.
