>evolutionary scientists aren't writing books called "the selfish gene"

correct. only one scientist wrote that book. had you read it you might have understood that Dawkins uses the term "selfish gene" as a way of expressing the gene-centred view of evolution (as opposed to the views focused on the organism and the group)

​

>being social just a tool to selfishly pass on genes.

so you admit that taking out the "social" part (so no genes are passed on) would end the human race? or how did you expect to continue? because, by your own admission then, being social is fundamental to human existence.
