Buddy, I get it. You're campaigning against antibiotic overuse. That's true. Antibiotics are over prescribed. I've never said they weren't.
What you need to chill on is giving people medical advice. I took a look at your post history, and this is a topic you're clearly passionate about
But you are not a doctor. You are not even in the medical field. It looks like you're an IT nerd. Which is great. We need nerds
But you espousing your opinions can hurt people. There are countless examples of people rejecting medicine that works, for essentially folk cures that do not. People die. Children are one of the most vulnerable to this, and I have personal experience with kids suffering because of people like you, campaigning against western medicine, convincing impressionable morons that alternative medicine works.
You are not a doctor, medical researcher, or a scientist researching bacterial diseases. You are a person reading what other people write on the Internet, and fixating on the gut biome above all other things is simply the wrong way to look at this.
