Hurling the epithet “creationist” indicates anti-something, particularly the descriptions of creation in religious scripture. Real science cannot discount the existence of beings in possession of power like that.
Caught my eye as I was clicking through the page. We sure have come a long way.
"Creationist" is not an epithet.
Indeed, I consider myself a "creationist", meaning I believe God created the Universe and everything in it, according to His plan, design, reasons & purposes.
But that is my religious belief, having nothing to do with science, and unconnected to any particular scientific assumptions, discoveries & theories.
Every week I learn new details of my religious beliefs from the pastor in my church.
If I may say so, the chief concern of church is not the "how" of God's creations, but rather: what is the necerssary response of humans to the Creator of the Universe?
Science merely proposes a few partial explanations for how the natural world works.
So, the word "creationist" is not an "epithet", far from it.
But it is a religious term, not used in natural-science.
Does that help?
