most of america was bound by the "grand destiny narrative" out of which came the notion of being american, american values and yes american culture. america is on the whole split into 3 main cultures, middle america culture, poor white and poor black culture. it has had spates of "other cultures" come en mass over its history and form enclaves, those have been usualy met with hostility and anger like the Irish were but are eventually consumed into the host culture.
multiculturalism is the specific attempt to preserve a foreign culture or many cultures inside a nation, in essence to avoid integration entirely.

why didn't you run for president then ?
You’re absolutely correct, though it is worth noting the grand destiny narrative didn’t go unopposed by either the new immigrants or those who preceded them. Americans are no more immune to the tribal impulses that evolved out of the last ice age than anyone else. This is evidenced by the pattern of ethnic enclaves which are established near point of arrival, and the flight of the previous occupants of these areas as the new arrivals become established.
Two things in particular have helped the US overcome these problems.
1, the 1st Amendment to the US Constitution and in particular the establishment clause. No more noble thing was ever born out of such hard necessity. It’s easy to imagine the founders as a bunch of homogenous,white, Christian men, but in the context of their time they were incredibly diverse. The difference between an Anglican, a Calvinist, a Quaker, and a Catholic were very apparent and mattered deeply. These men realized they had zero chance of forming a unified nation if the government were able to pick winners and losers with regard to personal expression and faith. By restricting the ability of government to pass laws that either oppress or pander to people of a particular sect, you create a culture where tribal differences are a matter of personal taste, not public policy. This in turn creates the sense among the people they’ve greater freedom to express their personal beliefs by obeying the law and staying off their neigbor’s lawn than doing otherwise.
This stands in stark contrast to Europe which swings from establishing separate legal codes to pander to certain minority’s cultural practices to banning things like head scarves depending on who holds political sway at the time.
2. (This one is shorter). The US is enormous, and economic factors make our population very mobile. This disperses people away from their enclaves lessening the influence of their respective tribes, creating a steady march to a more unified culture.
Is this your " I have a black friend defense", your "facts" are just a load of bull and contradict each other you need to pick a stance on what you believe in clearly you don't believe in judging people on a individual basis otherwise your past statements were just lies. You need to decide which you is telling the "facts" can't help you there, then again you are a Trump supporter facts, reality are not something you believe in only the Donald.
This is a bit of semantics, but I prefer to make a distinction between respect and courtesy. I offer former President Obama the courtesy of referring to him with his title, despite being ideologically opposed to him because the dignity of the office he held deserves it. I do the same for President Trump. Respect on the other hand is something I offer sparingly, as it must be earned.
