So now we are back to the idea that this coming from a lab is dangerous idea that shouldn't be talked abbout?

It was something to consider last summer but now it is a dangerous idea again.

We have become such a total joke intellectually.

No. We should consider all non-impossible hypotheses, weighted by their prior probabilities. What's dangerous is to proceed with sanctions against china without having an airtight case (with multiple cross-consistent supporting data inspecting by many parties). Nobody has made an airtight case that the virus was human-engineered (for whatever reason) or leaked (intentionally or accidentally). ANd it's most likely any evidence that did exist has been scrubbed.

However, that's all speculation, not fact.

Yes. That’s why so few dare think it.

No, it's not that they don't dare to think it, it's that they realize it is stupid.
