Umm, your quoted source is full of references to religion, so you're not even following your own guidelines.
If you note, the article was written by a member of an organization dedicated to secular humanism. Secular humanism and religious thinking don't necessarily preclude each others. By definition, what makes one a secular humanist is the ability to accept new evidences and adjusting their philosophy accordingly.
Saying that, one can still have a civil discussion about the topic at hand. Do not lie, the reason why religious discussion is a taboo on AllDeaf is because it usually boils down to a screaming-match "YOU'RE WRONG!" over interpretations.
There are some things that are factual however. Scientific advances always flourish in environments where they are secular. We see this repeatedly throughout history. In Greece, it flourished throughout the Hellenistic era.
The reason why sciences flourished during the Golden Age of Islam was because of a doctrine called
ijtihad [trans. "independent reasoning"]. They declined since the 13th to 14th century because of a shift to
taqlid, which in practice means obeying a higher authority.
Florence was largely secular too during the Renaissance during the 14th and 15th century.
We see a similar course of action under the Dutch Empire where they offered people refugees from the Protestant-Catholic War.
Similarly, the reason why Soviet and American sciences were so tightly competitive during the Cold War was because the scientific institutes in both countris were given some leeway in thinking for themselves; post-Stalinism that is. It's a bit of a misnomer to say Russian Communism prohibits free-thinking because the elites were largely democratic and for the most part they could speak freely among themselves; it's just that the commoners couldn't speak out.
So what David Niose is arguing against are people who see secular institutes as a threat to the survival of their theologies. One of the major arguments against secularism is the absence of a supernatural is a choice. It is not a choice when one realizes there is a natural order to things which can be explained without provoking the outerworldly. Doing so otherwise is sticking their head in the sand.
