I think that this reasoning about the hurricanes is coming from two sources. The ones who say Trump's to blame are still trying to blame Trump for everything that's wrong in the world...and that's just wrong. The "religious fanatics" (to borrow Frank Zappa's term) say that God is unleashing his wrath on the US, but I don't agree with that either.
While I have gone to church for a number of years, for some reason I've always believed that weather patterns and natural phenomena happen without being controlled by any deity. They are natural forces that simply are, with no divine intervention. Whenever I've read about God bringing heavy flooding or thunderstorms in the Bible, I just haven't thought much of it. That's just my personal experience.
We can have the whole "religion vs. science" debate here, but that would be utterly fruitless. In the end, I believe that statistics, scientific data, clear evidence, and TRUE FACTS are more significant and valid than any other theories that people are putting out there.
