newbee,
You’re the only person claiming that it was billed as a “dinner of kedusha and tahara”.
The promotion merely stated, “Rabbi Soloveichik will entertain and enlighten with a special lecture over dinner. We’ll learn about some far out there kosher foods, and we’ll eat a few of them too.”
It’s called a “Halakhic Dinner” because halachos are taught about what is eaten.
Was this entire thread just a straw-man argument for you to criticize other Jews and thereby feel good about yourself?
