The virus has a furin cleavage sequence. These are not natural to Covid and are a signature from genetic engineering.
It has to be an engineered virus.
Fauci knew this and suppressed the papers that discovered it, through bribery or threats to the scientists.
You’re incorrect about the furin cleavage site not being in these classes of some corona viruses.
If it was engineered it’s possible they put one in because of this.
But it’s not established it was engineered or selected via gain of function.
It’s possible but I have not seen the data.
I’ll reiterate, I don’t think it matters in that, natural isolate or manipulated, it came from there and was lied about and covered up.
