Preface: Going to be using pseudonyms.
After seeing what happened to person Z who was convicted of hate speech for making a Y joke, and for (me) being banned from site X for making jokes about topic Y. I pondered where is the line that defines hate speech to dark humor.
My personal belief, which ties in with a mixture of Australian law and American amendments is that you can criticize and joke all you want about anything, but as soon as you threaten or encourage such a thing to occur it becomes hate speech.
An additional question is whether the initial intention of the joke matters whether it becomes hate speech or a joke, this is in reference to person Z.
P.S I am not well adjusted to the intricacies of the rules here, if I can fully reference specific people/websites just let me know and I'll disclose the details of the pseudonyms.
