I don't think it's wrong to strongly dislike my dad
Why do you dislike your dad?
I just don't think it's wrong to strongly dislike him
Everyone dislikes their parents at times, but you should question why you think this is okay.  Your parents care about you, and want what's best for you in the long run.  You shouldn't resent them in general for what they have done.
I disagree. Parents are a duty and I have a right to hate mine.
You should consider all the things your parents have done for you and you should make sure that you do not disrespect them. I do hope you find it in your heart to forgive your dad and make sure you try to reconcile with him so that you would have a better relationship with your parents.
