Edit: Blocked the author's name, because it's not my tumblr. I didn't expect so many people to misinterpret it and respond in this way.
Edit 2: This is not from the same author, but it's a reply to them. I think it might help clarify the post for those that are confused:
I normally don't worry about usernames on tumblr, but since there've been some really out-of-pocket misconceptions in the thread, I don't want anyone to harass them.
No, they didn't, really. Most ashkenazi jews were converts. And also: european. There's a reason why yiddish is so closely related to German. And jewish cuisine is clearly distinct from palestinian cuisine.
Jewsin diaspora are exactly that: in diaspora. They belong to wherever they live. You can actually still see the hole in German culture which the Nazis tore by murdering/displacing so much of the German population.
Claiming that a people needs to have some country to be purely for them is nothing, but blood and soil ideology.
Zionism is about 50 years older. And there was a minority of about 20% of jews in the 1930s. To make it a jewish majority state, mass settling was performed.
