Why do some religious Jews eat pork and shrimp?

Re Chinese Food

Last time I was in Chinatown, I pointed out a kosher certification in a restaurant window. [Homer Simpson] Peking duck, sesame beef, fish tempura, sweet and sour chicken, General Tso’ chicken, red bean paste, those crispy noodles they always give you ahhhhllllll[/Homer Simpson]

Re White Steak

Why should it be insulting? While a Jew may be upset that another Jew isn’t keeping kosher, gentiles aren’t required to keep kosher.
