I know I'm gonna get blasted with "show me the receipts" and hard data for this, but spaniards are the most racist people I have personally dealt with. This includes incidents in college, stores, a concert and some guy who called me "Panchito" in the street.
Which would be, idk, normal if I was in Madrid, but all of these happened in Mexico. I'm not gonna paint them all as racists, but I'd lie if I said that I'm looking forward to travel to Spain or having to deal with someone from that country again. I'm sure there are a lot of cool people from there in this forum, but it was kinda tough to get talked like that in my own town.
