It's just not true that in the US your fellow citizens have suppressed bigoted thoughts. It's true that certain collections of people don't want to hear it anymore and act in a hostile way if they hear it. But the US is big and tons of places tolerate all kinds of things.
If you want to be my friend, don't talk about Jews controlling the world. My friends will probably have my back on that. It's not "suppressing speech" that if you're in my circles that kind of sentiment is not welcomed.
