Modal Argument: The Mind is Not the Brain

[Brakeman]

"-ism" refers to the ADHERENCE to a body of beliefs or a methodology. It's a choice in how to approach problems.

If scientisim = science, then atheism = atheos (no God). Few here will argue that, because it's linguistically unsound.

If scientism = using the rational observation methods in science, then Atheism = using the rational observation of the absence of god. I see no problem with that.

You don't just go making up words by slapping an "ism" on it and call it a religion or a "pseudo-religion." "Scientism" is a word made up by woo woo doctors to push a anti-science agenda. Even though it may be espoused by others, it is a nonsensical term as the definition of science does not lend itself to the creation of an "ism":
sci·ence
noun: science

1. The intellectual and practical activity encompassing the systematic study of the structure and behavior of the physical and natural world through observation and experiment.

The "ism" of observation called science, is just systemic observation, a behavior that ubiquitous in rational behavior. Whereas one could live to be an avoider of atheism, judaism, or whatever religionism you want, you can't rationally avoid the tenets of science in everyday life. You observe and react. You "tested" your understanding of the world as an infant and you continue to rely on the observational evidence you gleaned then.

Anyone that uses the word Scientism other than in jest is a buffoon.
