An ideology that excludes people cannot function sustainably.
When a society seeks to push away large swathes of its own population, we see a backlash. This was evident during the French Revolution, the anti-colonial rebellions throughout the 20th century, and in the reactions towards left-wing hegemony. What has become clear is that exclusion cannot be the basis of a society – but why, what is the cost if this warning is not heeded?
A stable society requires that all stakeholders are included in some way. This is the essence of democracy. A just society requires a sense of inclusiveness.
It is not so much that decisions need to be made through consensus, but that all stakeholders within a society feel that they are a part of said society. This can be accomplished through civic education, but also through costless mechanism such as simply allowing the vote or not actively working against said group politically. But even without a desire for justice, a society always needs this sense of inclusion, or we descend into rebellion and chaos.
If you don’t include people in a society, they will work against that society.
This becomes worse when entire groups are, as it is called, ‘disenfranchised’ from the institutions of a society. Individuals, too, often feel excluded from society, but this cannot be avoided. There are many that feel depressed, hard done by, or simply do not gel with a society. They are seldom a threat (but can be, with the case of lone wolf school shooters). The real threat is in the disenfranchisement of people based on group criteria.
When group criteria is used to exclude, especially based on something as arbitrary as race or gender, then those who are excluded based on the criteria will band together. It isn’t because they have any natural inclination towards unity, but simply because adversity from the outside does push people together. It is simply human survival instincts at play.
This is seen very poignantly in the creation of the European Jewish identity.
In response to the dictates and abuses of European society over the Jewry, communities of Jewish people banded together to defend one another and help each other. The Jewish community in Europe was tight-knit purely due to adversity. One could say that anti-Semites constructed the Jewish identity.
The Jewish community, in hindsight, didn’t suffer from banding together (but no doubt suffered from the exclusion and abuses by the states). What did suffer, however, were…
