Westerners generally, and Americans specifically, don't realize how their constant harping on "basic freedoms" comes across as ethnocentric. My parents are American citizens, but they were raised in Bangladesh and they don't really believe in free speech or democracy. My dad always talks about free speech with implicit scare quotes, like he’s referring to an american custom.
Rights are not given to you by your government, your rights are your rights by virtue of you being a human being.
Thinking freedom of speech is even remotely ethnocentric just proves that something is broken in that person's head that they don't even understand the basic concept.
Why? To what extent? There are multiple correct answers to these problems. The best universal one is allowing folks to migrate to a cultural configuration they like instead of dictating what values others should hold.
