If your parents I.e. your dad, tries to get you out of the fandom watch it right in front of both of your parents chances are your mom will be on your side so that's 2 on 1. If that doesn't work ignore anything your dad does or says if he takes your computer, find it and take it back, if he blocks the hub or whatever find the code and unblock it or you could take the rational approach and try to reason with him, tell him that I am my own person and I don't care what anyone does or says so if u can't accept me for me then you need to rethink your morals and stop badgering me like I'm watching porn. So yeah that has a good chance of getting him to stop being a intolerant jerk. When life gives you lemons make combustible lemons and burn life's house down.
