And even if you decide to leave the issue of slow-paced genocide through miscigenation aside...
Why on Earth do Canada and the US have to have one of the core components of any nation-state their (non-supremacist) racial composition destroyed by millions of immigrants with no historical right to live in North America whatsoever?
America has no historical debt with the people of Burkina Faso or Sri Lanka.
The only historical debt America had was with native americans, black americans, the original hispanic population of the Southwest and I would argue that this debt was reasonably paid to the point of causing blatant, overt discrimination of hundreds of thousands of white Americans and Canadians who lose college
and job opportunities every year to less qualified minorities.
Multiculturalism is a mental disease thinly disguised as a political ideology according to which western countries (and only western countries) have an obligation to destroy their own non-supremacist ethnic composition.
This is a direct consequence of the fourth social paradigm created by WWII I described in The Tremendous Power etc...:
4 - The redefinition of western countries as multi-racial nations without a predominant ethnic identity
Western countries were redefined as nations without any racial, ethnic identity and immigration laws were changed allowing massive non-white immigration into the US and Europe.
The tremendous power of the social paradigms created by WWII - Part I - The citizen
Throurought their history, the United States and Canada have always consistently said that their essence as western countries was their white majorities and ideals and institutions derived from the Renaissance and Enlightenment.
After WWII, all of a sudden:
OH!! We're sorry but for 300 years we've been committing a terrible mistake... the white majority was never really part of our foundations just the ideals of John Locke, Montesquieu and Voltaire...
This was an huge overreaction to the horrors of Nazi Germany... Nazi Germany had an overwhelming white majority... So instead of blaming solely Hitler's ideology and anti-semitism in general, the racial composition of western nations was blamed for what happened and deemed a risk to racial minorities, a risk of future genocides.
All that needed to be done after WWII was to teach tolerance and respect for minorities to the american and european youth.
Starting a process of genocide and destruction of their non-supremacist racial compositions was overkill, totally over the top.
No american president has ever held any plebiscite or referendum asking the american people's approval for the drastic ongoing changes in the country's racial composition. Much on the contrary, national figures like Lyndon Johnson, Robert Kennedy and Emmanuel Celler assured, promised the american people and Congress over and over that the 1965 Immigration Act would not "upset the country's ethnic makeup" (Kennedy's words)... The american people was shamelessly deceived, lied to by their political leaders.
No british Prime Minister has ever consulted the british people to see if they agreed to (the more modest) changes in Britain's racial composition.
When the rest of the world, China, Nigeria, Iran, see what's happening in America (and Canada), a country actively, willingly destroying its racial composition through mass immigration, without having any moral obligation to do so, they shake their heads in disbelief and think to themselves:
"
This country is batshit crazy."
This insane paradigm that preaches the denationalization of western countries, the cannibalization of their non-supremacist white majorities is precisely what leads millions of brainwashed westerners to parrot the grotesque aberration of thought according to which people from China and India have more right to live in America, Canada and Britain than Palestinians in Palestine (in conjunction with the other paradigms: the superhumanization and dehumanization of Jews and Palestinians, respectively).
