Anticordarians believe that it would be best for humanity if each person tore his own heart out of his chest and consumed it, after which time he will be able to live in true happiness. Until the body develops a self-healing mechanism that will allow the heart to be replaced by a system by which each vein and artery is able to keep the flow of blood passing through the body, however, anticordarians believe that the heart is needed and vital to keep the person alive.

So "theoretically" they are against the notion of the heart but de facto they are in favor of it. The fact that their premise runs counter to biology, evolution and a host of other principles is irrelevant because they hope that at some point technology can be developed to correct the problem they will create by removing the heart in the first place. A massive waste of time and resources to replicate natural processes based on an absurd ideology pursuant to which those natural processes have been labeled "bad".
