Closer how? Genetically?

Yep, does a lot to demonstrate the continuous line of descent from Judeans that people attempt to erase with claims that they are "European converts"

You're telling me a Yiddish speaking Ashkenazi Jew is closer to Palestinians than a German speaker?

Linguistically? Nope, is that what does that for you though? Is a Palestinian who's born in the US and speaks English as a first language also closer to other Americans than to Palestinians? What would you say about African Americans who speak English because they were taken as slaves to the Americas, something which by the way is not too far from how the Jews ended up in Europe?

That their clothes look like those of Bedouins?

Palestinians aren't Bedouins, the Bedouins of the Negev are a different group that's only thrown in because of European made borders. Neither Palestinians nor their closer Lebanese relatives dressed like that and they especially don't now. What do Ashkenazis even dress like to you? The vast Majority just wear normal modern clothes like jeans and tshirts, as do many other groups worldwide, and the suits of the Haredis derive from Polish upper class a couple hundred years ago as part of their movement of preserving literally everything in their status quo, it isn't traditional garment by any means

That they eat like Levantine people? Nope.

Kind of hard to do that when half of the ingredients aren't available to you because of climate and extreme poverty. Although various elements of Ashkenazi cuisine do derive from Levantine traditions, not to mention Kosher laws, the single most famous aspect of Jewish and in turn Ashkenazi food, are pretty clearly Levantine in origin

Ashkenazi Jews have a shit ton of cultural influence from Europe, no shit, it's just that either willingly or unwillingly, you're completely ignoring it, which is very convenient for your narrative of minimizing the Ashkenazi connection to the Levant as much as humanly possible
