We, however, live in an age when liberalism’s priests and priestesses no longer feign respect for the powerful arguments in favor of the reasonability of Christian faith defended, for instance, by Mill’s contemporary John Henry Newman in his 1870 Essay in Aid of a Grammar of Assent . They increasingly won’t even tolerate Christians living according to the principles of Christian morality. Witness, for instance, their efforts to narrow religious liberty to freedom of worship.

Another advantage is the modification of genetic traits in human beings. Human genetic engineering science modifies human beings genotypes before birth. This process can be utilized to manipulate some traits in people. Genetic engineering can be employed to suppress negative traits while boosting positive ones. Positive genetic engineering is concerned with the enhancement of positive individual traits. This includes increasing human capacity or longevity. Conversely, negative genetic engineering is concerned with the quelling of negative human traits such as some genetic diseases.
