To be honest, the "people don't believe in experts" thing really annoys me, this weird pride in ignorance is the biggest factor in the country crashing downhill in my opinion.
You had a guess about uk knives vs us mass shootings, fair enough. But after seeing you were massively wrong, instead of saying "I'm probably wrong" you seem to be saying "I'm probably right and the figures are wrong". Can you not see how nuts that is?
