The probability that this is true is very, very high, due to the source.
And you know this.
There is just no logic to the statement. (The fact that this at least could be true means everyone must “fight like crazy”).
That would mean that anything that “could be” true, should be treated as true - even if it would require extreme reactions (“fight like crazy”).
For example, it “could be” true, that your parents, children and spouse are about to kill you.
Therefor: fight like crazy.
It “could be” true, that the food, water or air supply was just poisoned.
Therefor: fight like crazy.
It “could be” true, that aliens are controlling our minds.
Almost anything could be true. That does not logically support a conclusion to fight like crazy - being crazy does.
The probability that this is true is very, very high, due to the source.
And you know this.
