Science Welcomes Open Minds.

Dogmatic bias against alternative ideas that are based on observational evidence and make predictions should be avoided.

Ethan's piece seems intent on discouraging people from getting interested in the the possibility that the dark matter is composed of stellar-mass black holes.

Most of the relevant evidence he cites is based on the assumption that the DM mass function is monochromatic. This is an unrealisitc and biased assumption.

If you are interested in other points of view here are some sources to check out to get the other side of a developing story.

There are multiple papers referenced in these sources that have been published in premier scientific journals.

A consummate physics fashionista should not be warning others that the theory of PBH DM might become too "fashionable".
