If we can't detect it or disprove it, it doesn't even belong to science. It belongs to the same realm as witches and demons - until some smart physicist devises

  We can disprove it, any one of the many, many lines of evidence that have been collected so far could have disproved the WIMP/CDM theory of dark matter. They haven't. Instead they've eliminated all of the other alternatives. That's science.

  You have to have a theory to test before you can test it. If they are stating as fact something that hasn't been proven, that's a problem. If they are testing the assumptions which closest matches the data, that is science.

  We can detect it, gravitationally. The Bullet cluster is pretty incontrovertible evidence that dark matter exists. It's detecting it through other interactions that's proving extremely difficult.

  The Higgs field was in the realm of theory for a long time. The maths matched up, but it wasn't until the LHC that scientists had the instrumentation to even look for it. Two other collides at the time through they were getting close, but it turns out the Higgs Boson wasn't anywhere near where they thought it'd be. It took a long time and a lot of work, but the experiments are reproducible (and they were reproduced several times to ensure they had found the Higgs and to learn more properties about it).
