That’s vapid rhetoric, you were demonstrably wrong since your claims were at odds with the dictionary, and your arguments irrational (as I demonstrated), and you laughably tried to claim to know the future. This isn’t only about being right though, it’s about having the integrity to admit when you’re wrong.
There are people who hide behind a misconception of agnosticisms of course, but that doesn’t change what the word means. We see theists and religious apologists try to peddle this one all the time, along with comparable semantics that try to present atheism as a claim or belief.
I would suggest you stop mimicking theists, with unevidenced hyperbole, and irrational arguments, and also have the integrity to admit when you’re wrong.
Like there, unless you can demonstrate a single example of me remotely claiming a deity is possible.
Or there, where you used an argumentum ad ignorantiam fallacy, and seem to think handwaving is a credible response.
Or there where you claim to know what will happen in the future.
Or there where you resorted to an ad hominem fallacy.
Dictionary definitions reflect common usage, so if one makes a sweeping claim that is at odds with it, then they’re wrong.
That statement is factually wrong, since one cannot claim to be an agnostic, and claim to know a deity is possible. I am an agnostic about all unfalsifiable claims, this includes deities, and I am an atheist, and I won’t believe anything is possible until it is demonstrated to be so, with sufficient objective evidence, and this includes claims for deities. Parenthetically I cannot claim deities are not possible, as I would need sufficient objective evidence to believe that as well.
