Not to be political but we literally vote blue and red in politics and that can sometimes kill people literally in wars and some die silent deaths because of the impacts of their policies.
I would say that its hard to underestimate the social estimates of these things. A person who will genuinely be impacted by it themselves would fall into these traps more than one might think. History has many examples of fascism that some suggest that these periods of turmoil are the norm rather than exception.
Once again an obligatory message about how the world faces some genuine issues but instead of fixing them as a civilization, We would much rather prefer to have scapegoats and this goes both ways and might be true in a certain way and at a certain path both sides are too extreme to ever collaborate for the most part that a nation of once great strength might die a slow exhausting death if nothing changes.
I have come to the realization, The world has always been like this and it might always be like this. Its messy but also one can imagine this as a side effect as the mere coexsistence of our species in such massive numbers might demand polarization.
Some people create initial changes (for greed, genuineness etc.)
people then follow it (true belief)
people then meet other people and become friends with them and create a community.
new people are born or who change because of the community aspect (Since most things are nuanced, it is easy to frame anything and sometimes everything into such communities.)
The original people who made the thing dies/are out of power and new people from the community join.
these communities gain influence and decide the decision making but the heads of such communities are prone to narcissism or any other ways to draft as much as attention as possible as it seems that all attention is (good attention??)
More corruption follows, even the people of community are impacted and they might hear criticisms but the lock-in is too much. Stockholm syndrome.
Everyone else face the consequence and someone new creates a new movement and create another set of intial changes. Competition between multiple colors follows, we also see cooperation between red and blue to prevent outside competition.
In such sense, change creates change and cycle repeats. It is up to our interpretation on if there is any idea itself which can remain logical if its implementation or implementors get corrupted in a sense similar to erosion of the main values.
more than anything, humanity wants a community. a human somehow wants acceptance and validation for himself and he is selfish in the sense that he will put a blind eye sometimes if he isn't virtuous to damage outside his house (sometimes inside as well) and he wants a community because that is the only way he functions within a society of millions and billions while monkeys cant operate on more than hundreds.
More than a political critique, my point is, we should be more aware of this human tradeoff from empirical evidences and open up this blind spot and perhaps be more aware about it.
