Hi Code Switcher,
Determinism, by definition, is not predeterminism. Nothing is established or decided in advance. This is a common mistake. So no, your response is not predetermined.
Your response is the caboose in a long train of cause and effect in your life. In this analogy, my article is the penultimate car of the train. You’ll either convert to determinism, so to speak, or maintain your faith in free will irrespective of my “attempting to persuade.” It will simply be time for you to convert, or it won’t. It may never be. Either outcome makes no comment on the veracity of the article’s premise; only the content of the article itself does that.
