Don't confuse the issue with facts! ;-)

Drop the d, add a g. I think that was I originally said, earlier. I
don't know, now.

At any rate, diesel, kerosene and jet A all absorb water, not leaving it

True, but that isn't what forms the contrails. The water formed by the
combustion process vastly exceeds will little was absorbed into the
fuel. That is the concept of importance. :-)
