Many people presume the left are pedophiles because they are "evil" and "demons" or "sick", etc... but there may in fact be a biologically (natural) driven reason for the left's push for pedophilia that is derived from r/K Selection Theory. The left are r-Selection and the right are K-selection.
The theory is observed in many animals throughout the animal kingdom and is a well-regarded theory though it has somewhat come out of vogue in recent times (that usually means it's right).
To summarize: when a group of animals have an abundance of resources and the animals do not need to compete over the resources, the need to delay procreation is significantly reduced. The reason to delay procreation for animals is to better ensure one's offspring will be able to compete for limited resources. If for example we did have significantly limited resources with intense competition for those resources, if a mother didn't instill values in their offspring to delay sexual gratification/procreation then that offspring would have less time to learn valuable skills (education, career, how to pick a good husband/wife), etc... then if someone did procreate young, they would be unable to compete for the limited resources and they would die along with their offspring. This isn't happening in modern society because of our social programs which ensures everyone survives. Furthermore, the significant socialist system (redistribution from rich to poor) that exists in our society leads to less competition and more abundance of resources for all. This is why leftists typically argue for communism because they want access to unlimited resources without competing for them.
Since we've now moved into well over a century of having too many resources without any competition, it makes sense that the r-Selection types are growing in numbers (leftists) whereas normally, they would die out in a more competitive environment and be unable to procreate. This leads to the proliferation of pedophilia because in the eyes of an r-Selection human, there is no reason to not procreate the minute you are able to.
If anything, on a large scale, a population shifting towards leftism promotes lower reproduction entirely.
The distinction between r and K selection is more based on a population's intelligence. And lower population also promotes higher birthrates, but these are times of "right wing" ideologies in which the idea of "equality" is minimal to non-existent.
