The college environment is getting really tense and scary?

I'm a friendly person, and there are some friendly people in my community college as well. But what pisses me off is there's a fair amount of students who are reserved, anti-social, and extremely competitive. They would "argue" with you in the cl for the sake of impressing the professor and/or peers on anything minor. I answered a question about the story we read, then the professor asked who disagreed, then a bunch of students raised their hands and rudely disagreed and gave their opinion. More examples of competitiveness is depending on the cl, it's very hard to "trust" a student to help you with something you don't understand or if you missed cl. Some students deliberately screw you over. Is this only in my college? Although it's a community college, it's one of the best in the state. Many students from this college transfer to top universities. What do you guys think? Is it still possible to make TRUE friends in this unfriendly, competitive environment?
