I mean, we fucked up the world for centuries so it’s gotta be pretty high. Would you blame Native Americans and indigenous Canadians losing their language on the English or the Americans/Canadians out of interest? We certainly got the ball rolling, but the new North Americans saw it through.
I don’t think the Aussies would agree with that! But I see what you’re saying, the English speakers were at fault, whether you considered them British or new world north American.
