I’m not “talking past” anyone, I was simply reiterating my basic point, which is all that needs to be said. He can talk all he wants, and it still doesn’t change the basic fact that a sentence should always ends with a Period (or some other punctuation), no matter what common usage at the time.

And more importantly, the idea that a Period carries emotional baggage like Passive Aggression is silly, and self-indulgent. Nobody should have to think about you that much that they should worry whether you’ll be offended by a period. If you require that much emotional maintenance that it extends to punctuation, then you are just a giant pain in the ass to everyone around you, and you need to grow up and get a life.
