As a 17 year old, can I disobey my parents, as long as my choices are Islamically allowed and with good intentions, due to the fact that I have my own thoughts and reasonings?
Bismihi ta'ala
Although you are your own person, and you think independently, and might even be wise in your judgments, but this still does not allow you to disobey or defy your parents. It is always important to align your lifestyles and decisions along with what your parents would be happy with. If for some reason they dislike or refuse, negotiation is always better than showing insolence.
With prayers for your success.
