It's sarcasm. Regardless of what a particular moderator might say, science is continually labeled a religion on science threads.
Evolution is so labeled because its findings are inconvenient to some believers. Evolution sprang out of geology, so geology is also tarred with the same brush. Geology bases its ages on physics, so physics is tarred with the same brush. Trigonometry finds a minimum age for the universe to be 168,000 years, so mathematics is inconvenient to religion. There is no branch of science that has mot been thrown under the bus.
