I'm not sure why we have gone from racism to sexism, it certainly doesn't support your perspective. Though i do understand why you have drawn a comparison, we should really stay on topic.
Do you think the reason you struggle to get work is because of your CV? Sorry if I have misunderstood and you aren't referring to yourself. Only I know plenty of successful minorities in plenty of different companies from communities all accross London.
We live in a predominantly white country, ofcourse that means opportunity for anti white racism is far less common here, however that isn't the same as it not existing here, and certainly no indicator as to whether or not it exists elsewhere in the world.
