thats just people being a richard. its not like ginger haired people had/have less rights
No, but modern day pride/rallies for loveuality, gender and (particularly) race aren't about equal rights anymore, as those have mostly been solved in the developed world. They focus on how those individuals are treated, and the prejudice they face.
And ginger people face no end of systemic, culturally-entwined prejudice, ranging from common verbal abuse, in person and even in the media, to physical and grievous violence.
