What would happen if i deleted an apple id off my iphone?

I recently got a new iphone. My dad was experimenting with and added his email claiming it was an "official" apple id. But thats not possible since my dad uses blackberry. I added my id and all my data is on my id, not his. I'm wondering what would happen if I delete his id from my phone. Would all my data be deleted as well? Since his id was the fist one that was added on my phone.

Should I switch from an iPhone to a track phone?

My parents always make fun of me for watching movies when I'm not. They tell me all I do is watch movies. They even tell other people all I do is watch movies. The thing is I've deleted every movie app on my phone about a month ago but they still don't believe me when I say I'm doing homework. My sister is very social and goes out on weekends but I do work. I just am sick of them thinking I'm watching movies when I don't honestly even care that much about my phone. I think I want to switch to a track phone so they will stop making these assumptions.

Please don't waste my time with stupidities. And if you don't know the answer, don't write anything. I'm not in the mood to see answers like "I don't know" or "not sure". So please don't waste my time.
