You're either a teenager or someone living a life of only pleasure pursuit.
Consider that whites are the only race to have such genetic variation in looks. We're the only ones with differing eye color and different hair color. The rest of the world has brown eyes and black/dark hair with a few exceptions.
Why is the rest of the world allowed to celebrate Asian, Black, Arab culture and race and not whites?
I like my race, our shared white ancestry, our long history of contribution to bringing the world forward.
Why am I not allowed to be white and happy about it?
You can be happy about whatever you like, Rusvik. However... you're conflating race with culture. And what you call 'white' is in fact 'mixed-race' (norse, pictish, gaelic, germanic, celtic, roman, greek, slavic etc etc). That's why we're so variable in looks.
I agree with Red Baron, probably in 10-15 generations, 'white' people will be a minority in metropolitan Western Europe and the US. About 30% of the couples my age that I know (me included) are in 'mixed-race' relationships. 20 years ago, it was almost unheard of. The future is coffee-coloured (and, to be frank, much better looking than its anglo-saxon parentage

).
One of the reasons England (which was, from the mid-1700s until the 1st World War, a pre-eminent global power) was so successful was the constant influx of immigrants, traders and invaders refreshing and advancing its culture and technology.
I'm happy about my culture's history, but I'd identify as British, not White... I have little shared history with people who happen to share the same skin colour but who live in Russia or America, for example.
