All those points are taken out of context and are misleading.

Are they still saying it’s “impossible” the virus escaped from a Chinese weapons lab?

As a biologist looking at comments like these make me concerned that the general public has not learned its lesson on pandemics yet. It is far more concerning our destruction of the environment and our encroachment of habitats will lead to way more pandemics.

I’m very much concerned with our government funding gof research in a foreign and adversarial weapons laboratory. Stopping that research would be a very important lesson to learn in this pandemic because it might actually be able to stop the next covid 19.

Yes, stopping such research is important.

But it has nothing to do with COVID-19.

Am I to believe that China was working on weaponizing a virus without also concurrently researching a cure/vaccine?

Virus provenance is important. It’s not a blame game. If it escapes from a lab they owe the world every piece of research they have on it but we’ll never get there if everyone says “hey hey let’s not play the blame game here”

No, you are not to believe that, there is no evidence for it. But there is plenty of evidence that nation states in general have done research on the weaponizing of disease.

Note that that doesn't rule out that it wasn't the case, but it is to the best of my knowledge not something that we have even a shred of direct evidence for.
