1. Gain of function research primarily uses samples collected from nature, and seeks to stimulate their evolution in as natural a way as possible to learn how viruses evolve in nature. If such viruses were to escape the lab, they would appear "natural"
2. It's not xenophobic for people from the US to suggest the possibility of a lab leak, because the US was itself funding gain of function research on novel coronaviruses in the Wuhan BSL4 lab
3. Lab leaks happen more often than most people realize[1]

And in there, I describe exactly how wrong your point 1 is. And how misguided your point 3 is.
The post also won a "best of r/science 2020" award!

The reason you will find extremely few people with actual credentials in the science we're discussing in these discussions is that working scientists don't have the time or will to get into these debates with people who wouldn't have the faintest idea how to actually conduct the research they're criticizing.
That post I linked took like dozens and dozens of man hours to write, workshop, source, and edit.
And I wrote it so I could link it in situations like this, and not repeat myself dozens or hundreds of times.
Personally, I'm studying for the biggest exam of my professional life at the moment, and I'm procrastinating here because I find these discussions so horrifying.
This entire thread could be a valuable case study in the Dunning Krueger effect.
Not saying it's not worth talking about, but rather that the amount of time and effort it takes to refute bullshit is several magnitudes more than the amount of effort it takes to create it.
In my case, that's 10+ years studying viruses so people on the internet with no credentials can tell me I'm wrong.
She's a geneticst or biochemist. She just uses some viruses in her research sometimes, like basically all biochemists.
Calling her qualified in virus biosafety is like saying someone with a PhD in Visual Arts is qualified as an expert in ballpoint pens because they've used them to draw. Sure they know some things about using ballpoint pens and which ones they prefer, but would you trust them to tell you how to design one from scratch? Or how to fix pens?
Not as much as some guy with a PhD in engineering and design at Mont Blanc, get what I'm saying?
I have also responded to her criticisms substance elsewhere, but she makes some big leaps in judgment that show she hasn't ever worked in a BSL4 lab before. Or studied the nitty gritty of virus genetics in nature before.
