Sure it is. It's an Okie's response to the rest of the world, just like Sooner--we ****ing OWN that word your ignorant mind thinks is an insult. As the line in Oklahoma Rising says, "I choke back the emotion, I'm an Okie and I'm proud, so when you call me Okie, man, you'd better say it loud!"
I'm trying to determine if you intended this post as an insult or not. That's how it reads.
I do not like the term "Okie," Period. I am the child of people who lived through the depression, though they chose to stay and nearly starve rather than joining the westward migration. I was raised on the doctrine that "Okies" were quitters.
As an adult, my ignorant mind did manage to pick up on the fact that some Oklahomans wear the term with pride. I am just not one of them. I usually just don't respond when the term is applied to me, but internally it grates on me. Not as much as being called ignorant, as your post seems to do, but it grates nonetheless.
I love Oklahoma, with all its warts, and it has plenty of those, but to quote the immortal Kevin Klein as Otto, "Don't call me stupid."
