"I was at school in the 80s. My brother was called the N word on a regular basis in school.""
I'm mixed heritage, but white. I was insulted via my Mother being "a n*** shagger". I was called all sorts, in the attempt to guess were my features originated from.The worse insult you could throw at a Woman in my area, in the 80's was saying that she'd have a black baby. if a Woman married a Black/Pakistan/Indian man she was viewed as marrying 'down'.
""But mixed race children often are very, very pretty.""
That's on a par with the 'jokes' about "them all looking the same" (black people). Children are often very very pretty, some are mixed heritage and some aren't.
""Racism can come from people of any colour and be directed toward people of any colour.""
It can, but then it becomes about the status in Society of the person being Racist and the receiver.
I've had the curiosity when traveling in the Countries mentioned, but as a British Citizen, I have a level of protection and my living standards will never be that of those people who are curious.
It is very different than an ethnic minority being verbally abused by white British Citizens in the UK, because help from the Police, Security etc might not happen.
""but I was called names for being white, “white honky” was one that I remember. ""
It isn't comparable, given that White people at the time were top of the food chain, as such.
