This is just a cheap excuse to shoot down differing perspectives. Yet, conceptual progress in science never comes from the mainstream. It always originates in well argued minority perspectives, which is exactly what this is. By shutting them down, you shut down progress.
Now, we wonder: why is the time since the 1950s so devoid of conceptual breakthroughs (not just in biology, but in science in general) while the first half of the 20th century was full of scientific revolutions?
