Everyone should hate Israel. It's a terrorist state built on ethnic cleansing and genocide. It's executed so many crimes against humanity since its inception that it's impossible to track them all."The jews" aren't a nation, there's a nation that claims to represent all jews and it's up to the jews (and only the jews) to push back on that.
I will repeat this question - do you hate Russians? do you hate Syrians/Alawites? Do you hate Turks and Iraqis for what they do to Kurds? Do you hate Japanese for what they did in WWII? Do you hate Americans for Vietnam / Afganistan / Iraq? Do you hate Chinese for Tibet, Xinjiang? Do you hate the British for Bengal Famine? France for Algeria? Pakistan for Bangladesh? Saudis for Yemen? Myanmar for Rohinja? Serbs for Kosovo? No. You hate on Jews. All of these conflicts have significantly more deaths than Arab/Israeli conflict. All of them are much more clear cut than Israel that defends itself since 1948 and Jews that defend themselves from hate crimes against civilians since 1920s.
