How can i talk my parents from going to spain again?? =(?

I really hate that country due to racism i received my last trip and don't want to put up with that s hit again!! I was aulted by two Spaniards throwing rocks at me because i am not from spain.. Were supposed to leave in april but every time i think of spain i get head-aches.. I also dont want my parents to be derespected either like they were the last time, they are going to meet a friend but i say they dont go due to the racism
