There’s a lot of confidence here for an argument built on some remarkably simplistic ideas about ancestry, nationality and history.
Having Russian, Polish or Ukrainian Jewish ancestry doesn't mean someone has no historical connection to the Levant, any more than having ancestors who migrated somewhere makes their descendants permanently “foreign”. History isn't a DNA purity test, and a 23andMe result doesn't get to decide who is indigenous to where.
You’re also making the rather bizarre leap from “I oppose the creation of Israel” to “therefore Jewish people who went there should simply have stayed in the countries their ancestors came from”. Given the centuries of persecution, expulsions and ultimately the Holocaust that shaped Jewish migration, that's an extraordinarily neat solution to a catastrophically complicated history.
And nobody needs to be told that Palestinian displacement and suffering aren't the responsibility of Palestinians. They absolutely aren't. But acknowledging that does not require pretending Jewish historical ties to the region are “homeland nonsense”.
As for “Zionism is to Judaism what ISIS is to Islam” — that analogy is frankly embarrassing. Zionism is a broad political movement with numerous strands, including secular and socialist ones, and Judaism is a religion and peoplehood. ISIS is a specific extremist terrorist organisation. You can be fiercely anti-Zionist without making a comparison so reductive that it collapses an entire political history into a terrorist organisation.
You’re entitled to believe Israel should never have been established. What you aren't entitled to is having your own version of history treated as self-evident fact simply because you've written “lol” after it.
