Why do the major social media platforms, like Facebook, refuse to take a hard line on virulent Jew-hatred?

Unfortunately, anti-Semitism is running rampant on Facebook, TikTok, and other social media platforms, from Holocaust denial to anti-Semitic tropes and conspiracy theories.

While Facebook announced it is banning “posts about Jews controlling the world,” other forms of hate don’t fall within Facebook’s definition of hate speech, according to its administrators, and is therefore permitted.

When will Facebook finally adopt the International Holocaust Remembrance Alliance definition of anti-Semitism?
