I see that your argument is a vacuous train-wreck. Multiculturalism equates all cultures, demanding that unsound cultures be accepted as sustainable. It's a deceitful rationalization, fraudulently advanced as a means to influence the ignorant.
It is certainly all that.
and since Multiculturalism is in the business of preserving archaic cultural mores, it is actually a very conservative ideology masquerading as a liberal. It's very purpose is to PREVENT backwards immigrants from accepting the liberal ways of the host communities since it operates on the assumption that rights are not afforded to the individual based upon any recognizable goal, but merely assigned by the subgroup as a product of custom.
It assumes that morality is entirely normative and that here is no such thing as moral reason.
Multi-culturalism does NOT seek to conserve anything. It seeks solely to deceive, through the use of wedging one unsustainable culture, into the target culture. It is a deceptive tool, fraudulently advanced ... as a means to influence the ignorant, toward the goal of undermining the adherence to AMERICAN PRINCIPLE.
Using the CONUS and Declaration of Independence define American Principles.
The Constitution represents the foundation upon which US Law rests. The Charter of American Principle was declared as the basis for the right of our founding Father's to govern themselves... the principles are set forth in that instrument... they were stated as follows:
"When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal; that they are endowed by their Creator with certain unalienable rights; that among these are Life, Liberty, and the pursuit of Happiness; that, to secure these rights, governments are instituted among Men, deriving their just powers from the consent of the governed; that whenever any form of government becomes destructive of these ends, it is the right of the people to alter or to abolish it, and to institute new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shown that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their right, it is their duty, to throw off such government, and to provide new guards for their future security. ..."
