I am not an atheist, so your strawman is rather inapplicable.
Newton was not a Creationist in any way other than that he believed that God created the universe.
Newton produced something of value when he sought to describe physical causes to physical phenomena, that is science, not creationism.
Anyone who believes that God created the universe is a creationist by definition.
Disparaging creationists as producing and contributing nothing of value dismisses the majority of people who have made any meaningful contribution to society and culture, because science isn’t all there is in this world and it isn’t what everything is about.
Creationists contribute in meaningful ways in all realms of life. Atheists are not the only individuals who are capable of making contributions that are of any value, which ism by default, what your position is with the blanket statements you are making about people.
Not very objective of you, I should say.
Is there any other way to define "creationist" allmendream?
I can't wait to hear further from you on this subject.
At the very least I am most glad to hear you acknowledge that Sir Isaac Newton believed in the Creator God.
I myself am convinced that he did. FWIW
