CNN is pretty centrist. Of course, it's a matter of perspective because a Fox News fan is going to think CNN is liberal, whereas an MSNBC Rachel Maddow fan is going to think CNN is conservative. That's how you objectively know that you're a centrist: when liberals think you're conservative, and conservatives think you're liberal.
Semi auto, auto, clip, magazine, bullets, ammo, it's all interchangeable to the uninitiated. I think we make too much of it.
I guarantee that we all use various terms and words incorrectly.

A semi auto is also correctly called an 'autoloader', so technically he isn't wrong. And someone who doesn't have a criminal record, under indictment, or under a restraining order, can, in Texas, buy an autoloading AR in less than 10 minutes.
