I experienced this exact phenomenon when I took a job in a new region (Pacific NW). Out of the team of 6 non-managers, half were amazing and fun people. The other three were myopic, antisocial assholes. Add to that my manager was an absentminded professor type, and his boss was super intense/smart, and scared the living day lights out of everyone because she didn't understand that new employees needed help understanding what concepts she was explaining. The point is, I was miserable, and after 3-4 months I knew it was not the right team for me. I found a new job quickly (networking, kids!) and once I found out my new start date I had a talk with my immediate manager and told him why I was leaving. I told him about the toxic culture. I told him about being made to feel stupid because I had tried to build process improvements which amounted to moving someone's cheese a few millimeters. He understood, and was grateful. I told the HR person about the team dynamics. I told her that this toxic attitude towards change would continue to drive talented people like me out of the organization. She profusely thanked me and said that it had been the best exit interview she had ever had. Fast forward 6 months on my new job, and I'm unhappy here for entirely different reasons. Time to start looking again! I absolutely do think you should talk to your manager. If you don't, you are missing an opportunity to practice the skill of having difficult conversations, and you're short changing whomever comes into your job after you, who'll have to have that conversation, too. Plus, your manager might surprise you. She/he might have a way to make you happy! Do start looking for a new job today. And for the love of all that's holy, make your next interview all about figuring out what the people will be like to work with. Don't come to the interview from a place of "I have to get this job." Come at it like a date. You're trying to arrive at a mutually beneficial fit. Don't try to impress them; just be yourself and see if there's a spark! You don't owe them anything in the United States unless you're under contract. What you kind of do owe them as a good person is to talk to your manager before deciding to quit.
