@FreeSpiritJen you’re quite right. Can you imagine the uproar if you said someone was too brown? 😮
Well exactly! If anyone said that, it would be classed a hate crime.
But people who are very pale/have ginger hair seem fair game. Unfair and wrong. 
I do also wonder if it boils down the historic dislike of Irish people. (And maybe even Scottish?) Very sad and nasty. 
The hatred towards ginger haired folk (from some) is bloody evil tbh, and so bizarre because they are so striking and attractive IMO.
Weirdly, the attitude towards ginger haired folk seems to be one extreme or another. It's either people who think they are stunning, and striking, and the pale skin and/or freckles are cute, and the green eyes (they often have) are attractive. 
OR, it's people who are vile and nasty and derogatory about ginger folk. Who bully and berate and mock.
Doesn't seem to be much in between.
And the 'are your pubes ginger too' comments are pathetic. How stupid are the people who ask this??? What other fucking colour would they be? Stupid cunts. 
I also know a few people who had people looking at their cute ginger haired baby, and tilting their head, saying 'awwww, oh no... poor thing. Gonna have a tough life as a copper top!' And I have also known several ginger haired women who were super grateful that their child was not ginger like them, but blonde or brunette like their husband. (Because of the tough time they had had as ginger haired people themselves......)
As I said earlier, I think ginger hair is becoming more 'cool' now and there are lots of famous 'red-heads' who people love and who are classed as cute or hot or attractive etc, but there is (sadly) still some prejudice and hatred towards ginger people.
As the OP said, any prejudice because of hair colour OR skin colour - ANY skin colour - needs to stop.
I don't think it ever will though sadly.........
