Become anti-alien fascist
In sixth grade I wrote an essay for my english class where I exposed to the world how I often fantasized that I carried an invisible crossbow and shot many of my middle school peers. Understandably my teacher pulled me aside and interrogated me to evaluate how mentally disturbed I was. It's a banal fact that humans (especially males) crave violence. The evolutionary pyschology basis for this wiring appears solid, the ancestral groups that took on active offense against neighboring groups were more reproductively fit.
Such violence is antithetical to a free market cosmopolitan economy. Those who give into such evolutionary violence urges are fated to be out competed by consenting positive sum thinkers.
Yet the violent compulsion remains key to so much of our pyschology. The free market has found many ways to scratch this itch for young men. Avengers, Jason Bourne, Rap, Heavy Metal, Assassins Creed are the outcomes from our desire for violence not its progenitors.
More nefarious groups have likewise harnessed our violent desires. Famously Nazi's and Mussolini's black shirts are fascist, but I think we should broaden that definition to include any group that uses in-group bias and a desire for coercion. We must therefore include gangs, ICE agents, the military, and Bernie Sanders anti-immigration stances as fascist. While not as extreme as Nazi's these groups appeal to new members by claiming you can become powerful and dominant over others through violent means.
Bernie Sanders inclusion in that list might appear to be so shocking as to be a mistake. Though the left is less overtly fascist than the right, the desire to gain power through coercion is robustly common throughout the political spectrum. "Tax the rich" and "eat the rich" are clearly different in magnitude, but the sentiment of seizing the outgroup's resources non-consensually carry a similar flavor of violent appeal.
Even subtler shades perpetuate motivations around even theoretically purely positive-sum practices. Silicon Valley creates so much value for the world, but its start-up cults are described as warring tribes from the steppe.
You've got to hate someone. As for me and my house, I'm with the Mormons and try to hate the natural man.
Unfortunately some targets are easier to hate than others. It's much easier to hate the Mexicans for taking your factory job rather than the subtle forces of sectoral economic transformation. The upshot: even when you try to hate abstract conceptual enemies like the Mormons do, you will still slip up and become violent against a more tangible enemy.
My tentative solution, when you feel like giving into violence, embrace an unironic fascistic hate for aliens. While we might need to expand the moral circle to include them someday, the jury still seems out on the matter. Though far away, they represent a real threat to everything you care about, unlike silly fantasy enemies such as [insert commonly hated group: jews, global elites, immigrants, the rich]. Let your burning hatred for aliens fuel your efforts to coordinate with other humans. Negotiate positive sum trade deals, spend more than selfish rationalism would dictate on positive externality products, dedicate your life to human flourishing. Because if we're going to crush alien skulls under our feet it will be because we will have learned that team work makes the dream work.
If we could socially or biologically engineer humans to not value violence that would be an instant win for humanity. Until we reach that blessed day, strive to hit the "good vs evil, IQ dectracting" button as little as possible. If you have to hit it, just make sure to label the aliens as the bad guys.
