You did not "read the passage" or else you would have understood the sentence structure.
"For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh.

(Many) deceivers are the subject(s), not unbelievers.
These many deceivers are the ones (who) confess not... (still deceivers here, no magical leap to unbelievers)
This is a deceiver and an antichrist. (the deceivers who confesses not...)
See? Nowhere in your verse does it say unbelievers are the anti-christ.

Check mate, now slink away...
God this is too fucking easy.

Or, consider for a moment how sentences are actually structured: Deceivers are the subject, confessing not of Jesus is the action that- in this case- marks them as deceivers.

Rather: there are deceivers in the world. What is the quality of these deceivers that makes them so? Not confessing that Jesus has come.

The absolute best that you can say, fishy, is that the sentence applies equally to both of our positions. But since mine relies on just my claim being true, and yours relies on mine being false- and it isn't- then the checkmate is mine.

Or you could keep cherry picking. I imagine you're good at it by now. Just don't expect those of us with working brains to be fooled by your selective reading.
