"shipping and blorbofication are not inherently at odds with understanding a story's deep themes" and "some people can't grasp the themes of a story because they never learned how to engage with stories outside of the lens of shipping and blorbofication" are two statements that can coexist
blorbofication to me is when you love a character in such a laser focus way that you somewhat detach them from the narrative from which they are inserted and treat them in a way roughly similar to how you'd treat an oc for which you still have no story and just like to put them in situations just for fun. which there's nothing wrong with btw, it's just that it can easily lead to people forgetting the character engine in a narrative and not just a barbie doll
