Actually I come from a family of people who either hide during the war (jewish/polish origins), or suffered from it. Maybe you'd also label it as "didn't have to struggle too much at life".
Eitherway, I don't think society was built to reflect the state of nature and competition. If you think struggle is good, I think you have some skewed belief of "life" in general. I don't have such belief.
Also comparing people and rabbits is really ridiculous. Even behavior psychologist and sociologists don't go that far.
So left vs right is a war between heritable different gene expression proteins on the most basic level. Different ideas and perceptions are only a byproduct of the effect these proteins cause.
And there's nothing inherently wrong with this expression. I'm just acknowledging that we are fundamentally different on the cell level and nothing can make us agree. Doesn't mean my expression is better than yours. These are just different evolutionary adaptations in animals that humans are part of. I have example of rabbits because they have furthered your type of "lifestyle" to more discernable level.
Also your eugenics argument is completely strawman, as is expected from you.
When will your book come out ?
