Conservatism is merely an intellectual manifestation of the psychological drives underlying a K-selected reproductive strategy. As a result, all Conservative drives will abide by the four main traits inherent to K-selected strategy, (ie. Competitiveness, abstinence until monogamy, later age at first intercourse (delaying mating until maximally competitive) and performing high-investment, two-parent child-rearing.)
The goal of Conservatism, like K-selection, is to produce the highest quality, instead of quantity, and to see it succeed in free, fair competition. Give children optimum rearing conditions. Make them as competitive as possible. Make the competition as honest and fair as possible, and see success/fitness rewarded.
The only real difference between Conservatism and the K-selected psychology is that Conservatism adds in our history of group competition (just a more complex form of K-selection/competition), adding a whole raft of pro-social drives designed to make us behave within a gorup so as to maximize group success. Politeness, decency, altruism/charity, loyalty, respect for authority in time of conflict, drives to punish anti-social activity, etc.
Abortion is about respecting compatriots (even unborn), high-investment parenting, and seeing everyone have a chance to compete fairly.
Gay marriage goes against the concept of marriage as a means of fostering high-investment parenting, with the optimization of the child’s rearing experience of paramount importance.
Affirmative action interferes in free, fair competition among men, and offers the prospect of rewarding failure at the expense of success.
All Liberal drives are outgrowths of r-selected behavioral urges. Like bunny rabbits, Libs exhibit an aversion to aggression/pacifism, embrace of promiscuity, support for single parenting, and ever earlier exposure of children to sexual themes and experiences. Their aversions to prosociality and drive towards disloyalty to in-group are just attempts to capitalize on the group competitive environment, through betrayal and selfishness at a time when everyone else is selflessly driven to altruism, loyalty, and violence. They are exploiters.
All of this comes down to r and K-selected reproductive strategies, and the psychological drives which motivate them. That they exist together in our species, and are so divergent in their nature is just an outgrowth of our unique evolutionary history. See www.anonymousconservative.com/modern.pdf for more on this.
I did not go for "more on this" at the pdf, but perhaps you can indulge one question.
These seem to be survival strategies of any competitive group. Is the Left pursuing a survival strategy or an annihilation strategy?
