Your claim that people have become intolerant of free speech is unclear. For example, speech which generates "vicious attacks" in response is still free speech. The responses are also free speech.
True threats should be reported to the police. That's not intolerance, that's just plain illegal. On the other hand if by "real threats" you mean hyperbolic threats, those are also free speech.
Free speech is not a guarantee that others must listen, or that they must listen patiently. That is not now, nor has it ever been, the definition of free speech.
