Racial diversity which means that apart from white guys,
Wtf are you talking about? The vast majority of the world is non white. Real diversity would be more white people, not less.
and they all live happily ever after because they are tolerant towards each other, not due to enforced antidiscriminatory laws but out of personal free choice.
Except historical evidence shows us that doesn't work. Modern day w Europe is the perfect example. The countries who embraced multiculturalism saw their rape rates, terrorism and violent crime skyrocket, tens of billions spent on people who don't want to work and expect everything for free and have turned parts of the country into no go zones. They don't even have enough respect to not litter the streets and not defacate/urinate in public.
Meanwhile Poland Hungary etc who have resisted multiculturalism haven't experienced terrorism, skyrocketing rapes, ridiculous unemployment among migrants etc. Poland took in 1-2 mil ukrainians and guess what they're not causing problems. Germany took in the same amount, but from turd world backwards countries with low average iqs and now theyre dealing with problems they've never had before.
Multiculturalism is an abysmal failure. And even a decade long Harvard study proves it causes more harm than good.
If you're going to push multiculturalism you should do it universally. Tell Israel to take in Muslims and feed and house them. Tell Africa to take in whites and provide for them and cover up rape stats. Tell Saudi Arabia to 'tolerate' gays. Let's see how that works out.
But no, to you only whites have to be multicultural. Do you hate your skin or heritage that much where you want fellow Europeans to suffer? Because news flash they are and an ever increasing amount don't want multiculturalism. Especially in Poland. If you respect democracy you'll respect the Polish majority's wish to remain homogenous and not take in turd worlders. But you won't because you think you're some Savior and everyone is wrong hut your multicultural agenda is right.
