If you're saying Christians shouldn't vote for Trump because he's white then you're racist and need serious help.
If you're saying Christians shouldn't vote for an American presidential candidate because he's American then I question your understanding of history and the current world order.
If you're saying Christians shouldn't vote for Trump because he's a racist then I want you to cite at least three links of verified incidents of Trump saying or doing racist things while in office. If you want to cite incidents from his entire life that's fine, but I am going to counter every one you cite with a proven quote of Biden being racist, and I've got 47 years of material to draw upon.
If you think as a Christian being proud of your country is wrong then you don't understand nationalism or Christianity. Nationalism is just that; being proud of your country. The Jews in Jesus' time were nationalists. They hated being integrated into the Roman empire, which was effectively the equivalent of globalism at the time. Jesus did not say that this was wrong, but he did discourage them from doing it violently, thereby condemning violent nationalism, which is a separate issue from merely being nationalist. As far as it relates to politics, the Biden and Obama administration involved us in far more foreign conflicts than Trump has, so a vote for Trump is a vote for peace.
If you think that being Christian means you cannot be rich and support being rich then you probably should know we dislike even more those who are envious of others' success. Opposing someone just because he's rich is the purest form of envy and no valid basis for a vote. As far as the election goes, we see Trump is rich, but Biden owns three luxury mansions and his son has evidently been entangled in a series of corruption scandals that, if proven true, will implicate Biden as well. Both candidates are wealthy men.
As I said before, I want you to cite links to verified incidents of Trump being hateful. I will counter every legitimate one with Biden saying something horribly insensitive and racist.
Jesus was a Jew of course, but his teachings led to the creation of Christianity, which went on to directly (and overwhelmingly for good) influence world history and culture. Being Christian means we follow the teachings of Jesus. That means we vote along his teachings. Biden claims to be Catholic, but Trump is the real Christian.
