I once asked a high elf if there was any parallel to the racism displayed by their city. He responded with the orcs. The orcs have a half breed and her children living with them. Somehow I don't think the High Elves would allow the same.
It's not that Orcs are racist, they just literally want to kill and destroy everything. Including, at times, their own species lol. They are racist in a way, but not like the High Elves.
