No self-respecting journalist considers Holocaust denial a legitimate point of view, and no serious media organisation argues that impartiality requires it to provide Holocaust denial with a platform in any serious discussion about Germany's extermination of Europe's Jews during World War Two - let alone equal time, or beginning and ending every such discussion with "Germany said".
Gaza Genocide denial, by contrast, is a well-organised and orchestrated global campaign sponsored, funded, and avidly promoted - without any hindrance whatsoever - by the regime perpetrating the genocide.
Serious media organisations not only consider it a journalistic requirement to give Gaza Genocide denial a platform and equal time, but they also routinely communicate Israel's talking points to their audiences. The BBC's compulsive resort to "Israel says" is a case in point.
The ICJ itself has already ruled, on multiple occasions, that Israel must implement a series of measures to ensure it is not violating its obligations under the Genocide Convention. Israel has dismissed these instructions out of hand and categorically refused to implement even one of them.
It is now widely considered a foregone conclusion that the ICJ will rule either that Israel's entire Gaza campaign constitutes genocide, or that specific acts and policies Israel has pursued in the context of its military campaign qualify as genocide under the Genocide Convention.
Outlawing holocaust denial is dumb as fuck.
Japan was literally worse than the Nazis during World War 2, but we can think or say whatever we want about them.
