First we have to define what is speech. I have done this before. Speech is a wide array of activities from body language to art. Is the blocking of such speech with extreme prejudice in the racial and genocidal men's rea Hate speech. If so is it so hateful that is can cause a serious detriment to society.
Hate speech is allowed to some existence. You have music groups, producers and artist who all hate something and express their views about it. However, once these speeches become a form of genocidal lunaticness like complete black balling of their existence. Then it becomes a massive detriment to society and to the entity that the hate speech is directed.
Thus, we then have to look at the groups being blacked balled from existence. First the Taiwanese government's idea of soverigntly Are completely blocked out over the web in which countries that the Communist provide main web services too. This means that a good majority of countries do not even know that the Taiwanese government wishes to be sovereign. As such, their representatives can't proper vote in the UN or other agencies as their people do not say much about it. The black balling of this information has gone as far as the CCP agents in countries actually collecting Taiwanese officials and helping them dissapear.
Well Falun Gong practioners are not only stocked in foreign countries as some kind of Jewish style resistance to the German Socialist Party. In which these practioners are then defamed and constantly tried to be black balled by Communist SOE and Polititribo officials in foreign countries. This economic hardship and warfare was also seen during the German Socialist Parties rule. In which German officials would use their massive SOE's and military might to force foreign countries to believe in their genocidal extremist views against the Jewish religious tone.
Therefore, if we take history and apply it to the present in analogous fashion. We can see that the Communists black balling of their existence on the web can be considered a major determent to society. As the CCP wishes to force them to die off, or even to become so muted as to not exist.
That is when hate speech becomes to the point of physical calamaty. For example, this cite is not hate speech. No where do I say that I know exactly how to arm people inside of Bejing with RPG's and Ak47's and plan to do it, in a genocidal fashion then to follow every single Communist offical inside of Bejing with birds and bugs, and then listen to everything they say. I know exactly how to do that. However, I do not wish for their genocidal destruction. I just wish for them to share their political power and stop using SOE's so the power balance can balance out as free markets do for Democracies.
However, I have enough information on this cite to start a genocidal campaign. However, I will not, as some of my old favorite board game buddies had their dimb whitted views of centralized fascist power and they where good folks, just had a bad thought in their heads. Till they found out who i was, and booted me like this last board game, I think it was more special relationship, GM wanted a smaller game though.
So, then we see that the CCP does wish for their existence and does constantly arm folks to take out the Falun Gong, and to arrest them not only in their domestic fields but abroad. In which we see a massive onslaught of genocidal activities where CCP agents try and get the foreign countries to oppress the Falun Gong exactly like the GSP did to the Jewish folks.
So is it hate speech to block the existence of their souls on the internet, I say yes. Is it detrimental, I would say at the point in which the CCP acts out along side the hate speech in action. Yes.
