An argument on a public forum is not won by whoever shouts the loudest or has the most "courage". If expressed clearly enough, it suffices (and is much wiser) to explain your ideas once and let the readers decide.
So I guess I won. The person I was arguing with called me a religious flat earther and then announced he was done with the conversation, rather than allowing me to reply. Age old forum behavior: Gotta get the last word and run. Sad really. If I was such a savage troll then just don’t reply!!!
