I disagree. It would be because you’re pro-science. Even your simplistic explanation about reacting to dead pathogen, and something about t cells and b cells, is a model. It underlies at least some class of hypotheses that are amenable to be proven wrong or augmented with further evidence. To believe in science is not to “know” static facts of a mechanism. It is to constantly reevaluate your best available hypotheses under the requirement of evidence. Memorizing facts often leads people into trouble. Creationist authors for a long time have given exhaustive biochemical accounts of the blood coagulation cascade as their own form of evidence of intelligent design. The statement of the facts has not much to do with science, rather it’s the choice to propose beliefs drawn from them, and whether this remains rooted in disconfirming your own hypotheses with intellectual honesty or becomes an unfalsifiable just-so story to reaffirm a believe you’ve otherwise arbitrarily chosen for non-scientific reasons.
