Our trust in Christ rests on the fact that He is genuine. He is "I Am". The real deal. We might bring subjectivity to the Faith, but that is while God, through Christ, is trying to wrap His truth around us. In the process, we are cautioned that there is a place where serving Caesar is legitimate, even God-ordained.
We must interact with Caesar in a wise way; his realm is problematic and strewn with fakery, but we are told to serve in that arena, regardless. Therefore, we should be careful that our cynicism about the political process not consume our primary passion, our God-given ability to love God and our neighbor as ourselves. Otherwise, the lack of objective fruit in our lives becomes the ultimate fake news.
Jesus warned that we must not position ourselves in a way that we effectively become flavorless salt. So, let's be careful that the volume of our dismay at the double-mindedness of this world not dim the message of hope that "has been shed abroad in our hearts by the Holy Spirit". Such dismay might be concerns about or even revulsion at political processes and allied social movements.
Christ in us, our hope of glory, is the primary mover and shaker. If we do not live in this reality, idols in the form of ideas become more than fake. They become an obsession, a place where faith cannot minister.
