I'm not going to argue the point, I'm no climate scientist. But Wikipedia https://en.wikipedia.org/wiki/Contrail disagrees with you as well, so you'd need to argue with their sources too.

"In general, aircraft contrails trap outgoing longwave radiation emitted by the Earth and atmosphere more than they reflect incoming solar radiation, resulting in a net increase in radiative forcing."

Shiny bright light goes through or gets scattered. Dull red blackbody radiation gets absorbed. Doesn't sound too counterintuitive to me, but again I'm no expert.
