Your refusing to accept science and continue to say prove it to me.
You really believe that your immune system fights off parasites, that you are constantly exposed to?
I don’t believe anything. I have educated myself in the subject extensively and can tell you have not.
Once you can explain to me what a major histocompatibility complex is; and it’s role in the immune system, and prove that I don’t understand it, then you can say I refuse to accept the science. Tell me what an IgE is. Explain it here so people understand.
Read the book I have linked, cover to cover. Then come debate about the immune system. Because you actually don’t know what you are talking about.
