One argument against this is to say the author doesn't like Trump politically. However, the author mentioned on another video that both sides are evil, but Trump is actually the anti-Christ.
I doubt he is the antichrist though even if there so many reasons to say so, but then again who knows, we are already in the end times with all these many wars going on.
I think the author is governed by political bias and his personal ideals, if Trump is the antichrist I don't want to imagine what Adolf Hitler, Stalin, Mussolini, Mao, or many other leaders in history were much worse than him.
It is laughable when I hear people ruminate on all these kinds of conspiracy theories. It is plain baseless and would continue to be unreliable without facts. Anti Christ might even be the kinds of life that we live that doesn't align with Christ's sacrifice on the cross.
