Nationalism is a political ideology that involves a strong identification of a group of individuals with a political entity defined in national terms, i.e. a nation.
It is not a way of governing. And in fact, as opposed to you saying nationalism and Fascism are polar opposites, Nationalism is in fact an integral part of what a Fascist is.
In fact, Fascism is in a nutshell, a radical authoritarian nationalist political ideology.
Fascists supported the unifying of proletarian workers to their cause along corporatistic, socialistic, or syndicalistic lines, promoting the creation of a strong proletarian nation, but not a proletarian class, through a revolution, and most preferably a youth based one.
Capitalism is flawed, the state would be run for the benefit of a few wealthy elites.
Capitalism is an economic system that became dominant in the Western world following the demise of feudalism. It is in no way a governmental ideology. A state can be capitalist, but also a totalitarian state, a democracy, a theocracy, a plutocracy etc. There is general agreement that elements of capitalism include private ownership of the means of production, creation of goods or services for profit or income, the accumulation of capital, competitive markets, voluntary exchange, and wage labor.
This does not necessarily lead to a few fat cats running the country.
Multiculturalism only brings violance, social fracture, economic collapse and a host of other banes.
Look up Singapore. Multiculturalism works. In fact, nationalism often does the above you mentioned, by creating an ''Us And Them'' mentality.
It is 'Us' and 'them', Nationalism saved Europe from WW1 and WW2, a truely Nationalistic state would not allow for a few elites to run the show as the state is Lawful (note, this is different from Legal).
No, it caused it. Recall the full Name of the Nazi. National Socialist Party. They aimed at German Nationalism, the superior position of Aryans over other races and hence viewed it as their right to take over land for Lebensraum.
I suggest you understand what in the world is a multicultural society before even posting further.
Multiculturalism is the appreciation, acceptance or promotion of multiple cultures, applied to the demographic make-up of a specific place, usually at the organizational level.
Nationalism on the other hand, aims to cultivate a SINGLE image for a nation, usually based on ethnicity, race, religion, culture, etc. In effect, Nationalism NOT Multiculturalism causes no diversity.
a truely Nationalistic state would not allow for a few elites to run the show as the state is Lawful
As above, Nationalism IS NOT a way to run a government, it merely aims to promote a single national identity.
Good grief, someone really has no clue about political philosophy at all.
