Of course they’re liberals. Rock-ribbed conservatives wouldn’t be producing free videos.
I’ve used some KA videos and they are pure instruction. Want to know how to perform an algebra function or what is Newton’s Second Law? Just watch the video. They aren’t like leftist public skoolz where every topic has to find a way back to racism, gay marriage, or global climate change.
That’s what I was thinking, just watch the videos and screen them for bias.
