This is not science fiction. This is real.
The speaker is saying they can prevent religious "extremists" by genetically lobotomizing people's sense of religion with a stealthy flu vaccine additive, or even the flu itself or an airborne rhinovirus containing whatever mechanism would turn off the gene.
If they can make adults "disgusted" with religion by turning off certain genes, what else can they do? Could they make people into docile sheep? Could they sterilize them?
This is so far beyond the pale of human rights. How dare they even consider doing this. And they wonder why people are suspicious of vaccines.
