What do I do about this talent competition?

If youR parents told you not to audition for a talent competition in the past and now they want you to do it would you be nervous? This competition is for a variety of different acts and I'm a singer. My parents told me I'm not what they're looking for. I'm worried that my parents are telling me to go on this competition so that they can prove their point? I don't want to be humiliated in front of everybody.
