Contrary to popular belief, the largest concentration of redheads does not exist in Ireland, but actually in Scotland. I know they're pretty much the same place but tell that to one of them and they will go all fiesty ginger on you, even the non-ginger ones.
Since ginger is the new n-word, a bunch of redheads decided to go all Martin Luther King, Jr., and march for equality on our homeland. (Side note: There should be a Birthright for redheads, the way there is for Jews to go to Israel.)
You can read more about it here. The march is meant to fight redism and make sure everyone understands it's as bad as racism before a Red Panthers group starts. After all, "ginger" is an anagram of the n-word.
