Humanity aims at belonging to some group but prefers to be identified with the like-minded. For instance, a person feels comfortable identifying with those of his language. Or it could be those of the same race or the same culture that one prefers to linger with.
The sense of belonging provides opportunities for racial divisions or cultural divisions. In less developed countries tribalism can be allowed to tear a nation apart. Nothing appears sinister when considering the fact that humanity craves belonging to some grouping.
However, there is a cause for every effect. Racial tensions are a product of solidarities structured from social preferences. Imagine a war of such magnitude as currently prevailing in Ukraine? There was a time when Russia and Ukraine were in solidarity. What happened?
The analysts suggest that the war was triggered by Ukraine’s desire to relate to Western nations. This points to some hidden animosity between Russia and Western nations, emanating from unresolved historical tensions. As Russia discarded communism, unacceptable to Western nations, one would have assumed such tensions would no longer exist.
Civilized as those nations appear to be, one assumes that communication would easily resolve such conflicts. However, humanity carries ego, impossible to handle easily. Solidarity with the like-minded groupings, rather than appearing as succumbing to strangers, creates tension. The sin of Ukraine was seeking solidarity with NATO, considered unfriendly to Russia, yet sharing the neighbourhood with Russia.
Differences, leading to stupendous conflicts can be tribal or as trivial as supporting rival football clubs. One feels threatened when existing among social rivals. It is often difficult to deduce which group to blame when violence breaks out between rival groupings.
None of them deserves blame, necessarily, as based on tastes. Someone may even feel uncomfortable when associating with disabled people. Yet others may prefer associating with such people, more than with the able-bodied ones. There is an aspect of confronting, which, humanity remains unaware of its significance.
