True, but it’s possible to ask questions that sway public opinion. Look at all the “studies” tobacco companies paid for. Or the racist scientific theories that attempted to justify slavery.
If you’re asking questions about a lab leak out of genuine scientific interest, that’s perfectly legitimate.
But if you’re asking out of a desire to win political points, stir up tensions, etc., that’s destructive.
There are plenty of actors on both sides, using the same tool of scientific inquiry for good and for ill.
