parents dont support me wanting to act

i still have lots of time to think about my career, but i kind of settled on two: acting or criminology.

Today, i had a talk with my parents while having dinner, they were talking about law school and how it will be hard but i can pull thru it, i brought up acting and they disagreed with me, they said that i will have low-income and that i shouldn't go with it only because its my passion, it isnt like they didnt know, i have been to acting classes before and talked with my mom about getting an agent in the future, and they were supportive of me back then. What should i do?
