Uttering death threats has never been protected by free speech.
It all depends on context. There are ways you can point a gun at someone in completely non-threatening and non-criminal manners (it's extremely common in the film industry). Likewise, there are ways to speak or write in completely criminal matters. Conspiracy to commit murder is one of those crimes. Threats are another.
In most countries, making racist comments isn't illegal. Of course, it can get you into a lot of trouble with the locals depending on who is present and who you're insulting (yay, more context)... Obviously this is true even in the United States.
