I'm going to be a sophomore in college and my parents still ground me...is that fair?

Hello, let me begin by explaining my situation. I am currently sixteen years old and I am going to be a sophomore in college next year.(yes, I graduated high school early) I go to school out of state, so I stay in a dorm room for the duration of the school year, however I come back home to Utah for the non-academic year. I grew up in avery strict, mormon family and I got in trouble for every little thing I did wrong. I thought that when I went to college my parents would back off a little, but they haven't. Last night I got home at 10:00 (curfew is 8:00), so now I am grounded to my room for the next month. I am in college! I think it isn't fair for me to get grounded. Do you think it is fair? Should I just accept the punishment and say nothing to them about it? Should I talk to them about it?
