Well no, we don't know where it's from yet.
I personally felt the messaging had always been that we don't know the origin clearly but there are a few possibilities, a lab leak being one, wet markets another, and bats a third.
I could see though how there could have been a "conspiracy" minded movement who'd start to hold strong beliefs of a lab leak and then mix that in with anti-asian racism and such. Then it becomes political, and probably people start posting things that make it sound like it is for sure a lab leak, and all that.
As an example, in more Chinese driven countries, I had read, there are lots of theories about how the virus is American made from a lab at the Maryland military base.
Basically all these conversations are about "pointing fingers" and "pushing blame". It's very political, and the truth will be hard to come out. Personally I think best not to care where it's from, we still have to deal with it none the less.
