Of course politics is everyone's business and should be a concern for every living citizen because we're all part of the process.
Politics exist because there are people which is you. Everyone in one way or the other is involved in politics, even right inside the family there's politics. And when it comes to Public Politics, it stretches way out to the our everyday actions(negative/positive) which all contributes to societal development.
However there are some factors that make people feel Indifferent towards politics i.e. Bad Governance, Unfulfilled Promises of those in power, Corruption, Electoral Malpractice, Ignorance, Insecurity etc...all these lead to increase in political apathy.
But regardless, well all should exercise our civil rights.
