Do you mean that you don't believe in the 10% apocalypse scenarios or that you think they're an acceptable risk? Only the latter is really "risk anything".
I would say I’m willing to accept the risk. But I do believe the risk is overblown. It’s always overblown.
I’m pretty sure they meant they believe in the 10% risk of everybody dying but are ok for all of us to take that risk without our consent because they saw a 4year old tragically die. Which sounds completely unhinged, to say the least
