I agree. We don't spend enough time teaching about the history of free speech in other countries like Germany. And no, I don't only mean in 1930s and 1940s Germany. I also mean the Germany of today. They, along with much of Europe, have laws outlawing some misinformation such as Holocaust denial and their societies haven't collapsed into totalitarianism.
Some restrictions on speech are truly dangerous. Some aren't. It is important to have the historical context to help know which one we are discussing.
