A good portion of mainstream American and European liberals would consider Jewish culture to be a real thing that deserves preserving, even while they claim that saying the same thing about any other culture or identity is racist
What is Jewish culture? Jews are as diverse a group as any other group. Jewish culture includes everything from religious nut jobs, to academia, to gay rights, to you name it. Jews are a extremely wide spectrum of opinion. Probably all spectrum of opinion is covered by Jews. So yeah let's preserve that. Let's preserve my Jewish culture, though I am not a Jew I share the same culture of all human opinions.
