Yes, I agree, ranting is not equivalent to screaming. But what you are looking for is something which can be as succinct as a well selected Reductio ad Absurdum …
Ranting can be more neutral than screaming, but so can sarcasm. Often the real intent (sorry, I’m borrowing metari1’s favourite word here; “intent”) with sarcasm or ranting is missed and it doesn’t communicate your point effectively to the opponent.
And, it might not look like it but I do rant. I just take a long time to get there.
