If you only see from the individual level, yes the individual genes residing in an animal that does not reproduce will not propagate. If you see it from an evolutionary biology (population) perspective it is apparent that it does not cause dead ends for a population. Mammals and birds engage in the behavior and they are successful at the population level. This makes it an inherent part of nature. It is degenerative at a population level only in the same way dead skin falls away exposing new skin at the individual level.

I suppose an excess of this exhibited behavior could be compared to eczema or leprosy given how you view the situation. However following the analogy, would you blame your flesh for its state if you were to suffer the disease? Also, who are you as an individual to judge what level of this natural phenomena is appropriate for society? As an individual, if you were given complete dictatorial power, how would you choose to combat this self-perceived scourge that ecologically creates space for those of different lineages you find less repulsive?

If I had eczema, I would focus on reducing the circumstances that cause flare-ups of this degenerative nature. I do find society to be structured in a way that creates much unnecessary suffering. There is a lack of community that has emerged from the degeneration of Christianity as a widespread social glue. "Don't lie", "don't steal" and "believe in the system (god, historically, was a symbol for the system)" are all crumbling. What steps are you taking in the world to help with this lack? (This question can be rhetorical or an invitation or a challenge depending on how you view it.) Faith without works is dead after all, wouldn't you agree? I have my works.

I guess my point is you are projecting your anger onto a perceived symptom rather than a cause. You come with no solution and negativity to something you see as a self-resolving problem and you cause division. I personally find those projecting anger and disgust where it will not help to be a symptom of lack of critical thinking in this society. Probably stems from our obedience oriented indoctrination camps (both public and private) during the youth's developmental years.

If we all could think a little deeper, work towards what we perceive as possible and blame a little less I'd wager things would improve. But what do I know. I'm just some dude on the internet.
