As everybody knows, back in time, meat couldn’t be conserved properly and this led to major diseases affecting people, so that it was highly recommended to let as much as blood out the animals before eating them (since blood attracted bacteria). Now, technology has evolved, we have fridges, we have conservations techniques and we can keep meat and everything else "fresh" for a long time.
My Question is: Why hasn't also our religion evolved like everything else had?
Why are we always attached to rules that at this time wont have any bad effect on us. Isn't everything that is made haram in the quu'ran made by the purpose of avoid it since it's bad for us.
How can eating meat that is healthy and clean bad for us in anyway?
