Off the top of my head, I don't recall ever reading any of your other posts (I could be mistaken), so it would be a combination of the latter (the scriptures you referenced) and just the way that conversations like this normally go.
If I was wrong in my own assumption, then I apologize, and I'll certainly consider your clarification of your own beliefs.
That said, Acts 8:17-18 doesn't specifically mention that they spoke in tongues. Granted, there was apparently some sort of outward manifestation that even Simon the sorcerer took note of, but it could have been something else (like prophesying, for example, as happened in Ephesus with Paul and certain believers).
