You don't happen to go to Eric Kelly's Cherry Street boxing gym, do you?

I'm kidding. But if you watch that video, I wonder if you might see some things in common with your gym experience.
Coaches can be intimidating. They push you. Usually it's because they want you to step up your game and learn quickly, because they believe you're capable of it (they see your limitations as being more "mental" than physical in that case). Other times, like in the video above, they just don't like you and want to give you a rough time.
If your coach is teasing you for using "big words", then it sounds like he might have a problem with educated, white collar people (assuming you are one), or people who are just more cerebral and want to know why they're doing stuff. Or he might have you pegged as some other "type" he doesn't think should be there.
Like in the video, the guy may think educated, white collar people are too soft, too casual, and maybe not willing to take a punch and get bloody. In other words, not cut from the same cloth as he is. So he might hold you in contempt.
I'm really guessing on this, though.
Either way, I think what happened to you is unprofessional. And I would walk. I wouldn't come back. I don't care if the instructors there have trained dozens of professional fighting champions. If they can't relate to me in particular and know how to motivate me in a positive way, then they can't coach me. It's their failing, not mine.
As for using too much force, yes what you described is consistent with a coach who thinks you're using too much force. Usually they do partner you up with someone who's going to hit you hard until you've had enough.
Then again, it could just be that the coach doesn't like you. I'm just guessing, but what your coach might think about you is that you think you're superior and have an attitude. I'm not saying you actually do, but he might think you do. In that case, putting you up against someone who's in a completely different league in terms of physicality and skill level would be their way of confronting the attitude they perceive from you.
I'll just add one more thing. Every gym has a culture. For the first few months, each newcomer there has to learn that culture. There are a lot of unwritten etiquette rules, such as how often you should verbalize what you're thinking (some coaches look down on you talking and prefer action instead). There are people there who don't like conversation at all. You might be looked down upon for wearing clothing or other gear that's overly expensive or something only really advanced people generally wear. Everyone in your gym could have very short haircuts, while you come in with your long hair. Etc.
Those are all things that you're supposed to pick up on in the first month or so. It's the culture. And you would be better off trying to blend in. If you can't, then you might want to go elsewhere.
Before you quit that gym, though, you might want to talk with your instructor and ask why he set you up with that pro fighter. Start the conversation by telling him that that guy sure did kick your butt, and that you're not in his league. Then ask why. With that humble admission, he might be more willing to open up about what he really thinks about you. If it goes down hill again, just walk out and never come back. It's simple.
Hope that helps.
