I'm going to date someone that everyone disapproves
Why would date someone that nobody wants you to?
I like power plays. I like to see people react when someone does something unexpected
That sounds like a bad idea. Everyone is giving you advice on this person for a reason and things might turn out badly if you ignore their advice.
Nah, I'm going to make them all mad after my relationship.
You are just playing with fire and wasting your time. Knowing that the relationship won't work just to spite everyone.
