I've thought about this for a while to be sure I'm not just being reactive. I wouldn't ask you to stop, in fact I encourage you to post more. I can't find the time to write such well written replies. Your post is the type of content I like to see and I'm sure others do too.
I'm giving you an unsolicited critique of your comments. If you intend to communicate with laymen about scientific concepts from my experience you're going to have a lot more success approaching it as if you're a supportive teacher rather than trying to prove someone wrong. If you try to be more like Ms. Frizzle than Sheldon Cooper you might reach more people, which is the ultimate goal of communicating science to laymen.
You are actually very good at it, and I encourage you to practice and find what works and what doesn't. Proving someone wrong just makes them defensive, teaching someone or communicating with the public shouldn't make them feel the need to be defensive.
It really reminds me of all those static and velocity pressure calculations I had to do in undergrad, until I got the degree.
