If you think there’s any “context” where it’s acceptable to make a reference to Aunt Jemima in a thread discussing the first African-American first lady, you really are clueless.
I think the Admin Moderator explained the context quite well. If you have a problem with that explanation take it up with him/her.
Oh, but you're not understanding the context! The context is that she should just make more pancakes and everything would be OK. That's not a racist non-sequitur at all. In fact, I often say to random people on the street, "you should just make more pancakes!" I usually get funny looks but little do they know that if they only took my advice, their lives would be so much better.
