Dark matter is easily the most popular theory for this observed phenomena, so clearly most people do NOT think having "something that interacts with fewer forces than normal matter is more complicated than Jerry rigging a change to the elegant general relativity." I'm not sure if you are saying that I think one is more complicated than the other because I do not. I'm simply wondering about ideas and asking questions. Surely we should still ask questions, right?
