That is a completely separate problem, and it's dishonest making the comparison. Extremist right wing ideology and genocide is actively advocated on /pol/ as well as anti-Jewish rhetoric. Neo-nazism is not pointing out Israel's war crimes, and pointing out Israel's war crimes is not neo-nazism or anti-Jewish. /pol/ isn't antisemitic for Israel's genocide; they just hate Jewish people.

The Trump administration trying to deport people for doing so is also unjustified. People are freely criticizing Israel on other popular social media (notably TikTok and Instagram) without inciting a modern neo-nazi and right wing movement like what has happened on 4chan in the past 10 years.
