Dont give a shit.
If all he does is belittle you, and you dont like it, dont give a shit about what he thinks about you. If he doesn't like your answers, or what you have to say, then just participate to the degree you need to and dont give a shit about what he says. That's how I've always handled that kind of stuff and trust me, not giving a shit about what others think does wonders. It got me the National Honor Society because all I cared about was doing my work. There's no real reason to file a compalint either, he's just doing what instructors do. Their role is to be hard on you. Only thing you can really complain about is if he sucks at doing the job.
