blimpI don't think you would say that, although some people I used to know said things like that in the 1970s, although it is at least "non-PC" surely!
I am not sure though that everyone is sure what multiculturalism is (as opposed to monoculturalism which a completely different kettle of fish) which is just the state of living in a society with a number of cultural influences or to use just one dictionary definition:
multiculturalism
/ˌmʌltɪˈkʌltʃərəˌlɪzəm/
noun
1.
the state or condition of being multicultural
2.
the policy of maintaining a diversity of ethnic cultures within a communityAnd, okay, you are allowed to not be a fan of it but it has nothing specifically to do with communal life and sharing or "religion coming first" over the nation and I think it does work as the United Kingdom and the United States, for any problems they have were founded as multicultual societies as were England, whose populace at its founding had numerous Anglian, Saxon, Jutish, Southern Brythonic or Cornish, North Brythonic/Cumbric (Welsh and Cumbrian), Norse, Norse-Gaelic, Cambro-Norse, Anglo-Danish and Anglo-Norwegian communities that while roughly grouped into three Norse, Anglo-Saxon and Brythonic were as different as the two cultures of say English and Punjabi, and Scotland whose ethnic groups were, and are, Gaelic, Norse-Gaelic, Anglian, Cumbric and Norse. There are problems from it.
As for "Liberté, Fraternité and Égalité" (which the sociopolitical system of France (a country I am fond of) does not tend to represent for much of its modern history), all I have to say is good old Robespierre, the leftist radical who actually first used the slogan which gained widespread use as the slogan of the Jacobin dominated Paris Commune and then Republic where sharing and communal life were de rigueur.
This was in reference to concepts defined in the 'Déclaration des droits de l'homme et du citoyen' which defined them as:
Liberty consists of being able to do anything that does not harm others: thus, the exercise of the natural rights of every man or woman has no bounds other than those that guarantee other members of society the enjoyment of these same rights.
Equality means the law must be the same for all, whether it protects or punishes. All citizens, being equal in its eyes, shall be equally eligible to all high offices, public positions and employments, according to their ability, and without other distinction than that of their virtues and talents.The fraternity part wasn't as well defined but was meant in regards to comradeship with the republican revolutionaries and to be blunt, "toe the party line" and was best expressed at the time as "Fraternité ou la Mort" ("Brotherhood or death!"). This would probably be considered "politically correct" in the correct socialist-feminist sense which refered to extreme adherence to party dogma rather than specifically going to an ridiculously extreme length so as to not offend.
No offence to anyone (or is saying that too PC?) but I wouldn't throw around the term fascist lightly (especially as fascism is a definable and terrible ideology) while using the buzz-term/sneer/conspiracy theory "Cultural Marxism"* which actually originates in fascist and other far right-wing circles as a derivative of the Nazi propaganda term Kulturbolschewismus (literally "Cultural Bolshevism"). I don't think it is PC to suggest that it would be a better idea not to use an element of NSDP propaganda in a debate on political correctness that started due to two people affirming that hey don't favour the 1940s over the modern era, as soon as someone states he is a socialist; while ironically complaining about fascism. Also which is Marxist or Fascist as both are distinct and highly contradictory ideologies**? Which is a moot point anyway as no-one is pro-PC to my knowledge.
*William Lind was the man who popularized the term in the 1988 speech 'The Origins of Political Correctness' which an be found here
http://www.academia.org/the-origins-of-political-correctness/ (I now need a shower!).
The other use, of "cultural Marxism" (with a lower-case "c") Trent Schroyer in his 'The Critique of Domination: The Origins and Development of Critical Theory' which was a criticism of the Frankfurt School for not being orthodox (in a Marxist context enough). Due to this usage the "Cultural Marxist" conspiracy theory that attributes PC, Feminism and sexual education and all "societal ills" to a Marxist and traditionally, usually Jewish (Lind:"How does all of this stuff flood in here? How does it flood into our universities, and indeed into our lives today? The members of the Frankfurt School are Marxist, they are also, to a man, Jewish.") conspiracy for world domination was attached to the Frankfurt School by the far-right and gave this red-scare theory a new lease of life. Regardless this is a debunked conspiracy along with most NWO-style theories and is not taken seriously by mainstream academia... who aren't all Marxists I assure you.
** And yes I am aware that some consider them both as bad or both evil or both to have caused a lot of death (unlike mainstream capitalism of course...) or whatever but we are talking about specific ideologies on different extremes of a political spectrum.
