My parents vs. the church?

So to make a long story short, I've been going to this one baptist church since I was born. My grandpaw is the preacher and my dads a deacon. But we've never really had any youth at my church besides kids that were much younger than me. Well I have a boyfriend who goes to another baptists church in our area and I went with him to his youth serivice this past week and loved it. It was more of a spirtual uplifting than I've had in a while. I would love to start going there to youth every Wednesday night. Now here's where the problem comes in, my church had services on Wednesday night too. I asked my parents if I could start going to youth on Wedensday and they said No! I mean like flat out no. Not even a maybe. Just no. This made me mad but the thing that made me mad the most was something my mom said. She said she didn't know anything about the church and I asked her if she would just come on Wednesday and check it out and she said no that she didn't have to and she wasn't. That made me so mad. It's like she's not even going to give it a chance. Her and my dad both just have this mind set where this church is that only one that I can go to and there's no where else that I can go. They're so closed minded that it's not even funny! Now I have no idea what to do because to be honest, I get a lot more spiritually out of going to youth than I do going to any service at my church. I feel like I'm not getting anything. So if anyone can give me any advice on how to deal with this that would be great, cause I seriously think I'm about to pull out my hair because of my parents and there close mindedness.
