People who talk about genocide usually agree with the whole river to the sea thing which is literal genocide.
For anyone else reading who is unfamiliar: "from the river to the sea, we will be free" is a slogan used by many Palestinians that refers to their desire to have a single Palestinian state with no Jews at all. It is a call to violence.
If you're just reading the propaganda and think there's a literal genocide going on, go ahead and read about the Armenian genocide. Then compare the actions, and how many have passed. Israel sometimes has incredibly oppressive policies, but they are far from a genocide and raising that accusation is particularly hurtful given the Jewish people's history of the Holocaust.
Yeah, the misleading headline/tagline are 100% on the site. Heck, the community rules require the title to match the article, so it's not like you had an option.
Feiglin is a nutjob, but he's unfortunately a shrewd politician and Israeli politics are currently dominated by finge nutjobs.
In general, calling someone a diplomat implies that they are currently representing the State. While it is an impressive qualification, and Italy is not a minor posting, he would face very real consequences for saying those things if he were currently holding that position.
That ultimately is kind of the point: neither of them will face domestic consequences for this. One has always been at the fringe shouting hateful stuff, and the other works for a right wing newspaper as an opinion writer.
