Idk why you're saying "you" when my flag clearly references that I'm not American, just defending the nation.
but no they dont dominate "being obese", For the most part those are all african countries.
As with diabetes, United states aren't even top 10.
Worst healthcare definitely not, it costs a lot but it is actually some of the best healthcare quality in the world, and the fact that it costs a lot is semi-aided by the fact that general tax rates that dont contribute to free healthcare are very down in comparison to countries that offer free healthcare, for example, Canada.
Gun violence, Definitely don't dominate, but yea its pretty bad.
Not a single chance you're going to try to bring up "innocent lives lost" in a Europe vs America conversation LMAO... You do not want to get into mass genocides as somebody taking the side of Europe.
Europe conquered and colonized practically the whole fucking world, caused both world wars, and are actively at war right now... and who are the victims of that war begging for the most help from? Canada and America lmao.
(I brought political things into it because lil bro up a few threads said "NA doesn't dominate anything at life in general")
