Sadly, redhead hate has been around for a long, long time. I remember an ad campaign from when I was a little kid that went, "The redhead is dead!" It was for dark hair dye. I doubt I could count high enough at the time to realize the number of times someone yelled that slogan at me.
This is why my primary identity is, and always will be, "Redhead."
Dogs and nature abhor a vacuum.
