People being people, I think. As much as we want to believe we can be united as humans, we don’t think, feel and believe in the same. Some are content being sheep and some are not.
As history recycles itself, our lives are also too short that we can’t see to it that we don’t redo the past after 4-5 generations. But the tides always change inevitably. we are living in a time where we might live through that change that’s unfavorable to us and that’s why it’s frustrating.
