As an American happy to live in a country with all our protected freedoms, there are some parts of the Constitution that other reasonable countries don't agree with, and that's fine. There are other cultures with other value systems and they're no less valid.
(1) Freedom of Assembly, part of our 1st Amendment, is one example.
A French court recently decided a protest in Paris could not take place. The court rationale was that a previous protest a few years ago in the same area on the same issue led to violence and destruction of property.
The French Constitution allows freedom of speech, but not freedom of assembly, and Americans are often confused by that. The freedom to write and say what you want does not equate to the freedom to protest in the streets. Not allowing freedom of assembly would have saved many lives in the protests that have swept the US, though potentially at the cost of slower social progress.
(2) Right to bear arms, our 2nd amendment, is another example.
The vast majority of first-world countries don't agree that the right to bear arms is an inalienable human right in today's society.
As Americans, we may prefer the added protection against government tyranny and our personal ability to protect ourselves and our belongings. Unarguably, however, it comes at the cost of mass shootings, and additionally, though many factors are responsible for our uniquely high homicide rate, easy availability of firearms certainly does not help to curb it.
--- All this to say, many of our protected rights have clear, substantial disadvantages. It's not our place to tell every other country in the world how to operate.
