There is a reason why countries in Europe have such laws. US did not have a major war for quite a while on their own soil which affects your thinking. We do not want to reignite national socialism or communism, we do not like to see news channels lying to us. We do not like Russian bot armies spreading propaganda in chats.

What truth is it that you cannot say in Europe? You can say pretty much anything and be critical and nothing will happen to you. And if something happens there are instruments like European court system which you can use to fight your case (there is no need to be rich for that).
