That user just posted that Imgflip just made national news. I checked and he's right. I don't think this is a coincidence. I'm really starting to believe imgflip is the CIA.
A republican person resigned because of that image. I think it was done to distract from another one of Omar's anti Israel statements. It's easy to find the imgflip story on the news and difficult to find the stories of the comments she made. Definitely an optics operation.
