Many leftists have abandoned Judeo-Christian values and have placed humans on the same level of animals.
For them, there is no God and therefore human beings are simply material, a bundle of atoms.
With the denial of the authority of a higher being, leftists make decisions based on their feelings alone.
More people believe that it is wrong to experiment on animals in order to save human lives.
Various genocides around the world, including the Holocaust, should demonstrate that rejecting Judeo-Christian values rejects mankind’s exceptionalism and higher worth.
