Are not synonymous terms.
In the post and in the comments they seem to use the term fundy and Christian synonymously. As if we were all the stereotypical “Dont think, don’t doubt, don’t ask questions” fundementalism.
Have these people never heard of theologians? Christian Mystics? The Great Literary Tradition (including pagan and political areligious works) we’ve preserved in our monastaries? Do they realize that We created the concept of the University?
Yes, there are some ignorant people who choose not to think. But we, Christendom, as a whole have done our fair share of thinking and deliberating.
