The stupidity of some shouldn't be an argument against the rights of everyone.
which societies, which failures, which "every" are you referring to, exactly?
I'd argue American society is currently failing. We're losing wars. We're racking up debt. We're destroying our institutions. A decent fraction of the population not only expects civil war, but cheers it on.
Meanwhile, in Europe, a similar vein is consistently emerging across the continent. It's done better at resisting. But in part through policing speech.
They're racking up debt too, with worse means to pay it back, they've destroyed both their institutions and their culture via mass migration of unskilled and dissimilar peoples, and they couldn't even fight a war because they can't field the firepower of one US state's national guard base (much less "lose" it, in the ways that people mischaracterize the US's recent conflicts).
Europe is a distant third in an increasingly multipolar world that will be shaped by the US and China, reliant on the US's increasingly fickle protection from Russia; aging, fading, and losing identity. Their core industries like automotive have already lost to China, their power costs are skyrocketing, their technology (outside of some gifts from the US like ASML) lags the US across the frontiers, and there are deep divides across the continent.
But hey, at least they are protected from misgendering a "woman" with a beard or mentioning the identity of a criminal.
