"OK, show me. Tell me a country that hasn't provided successful immigrants to the USA."
I had also written "Your anecdotal evidence doesn't prove anything. Of course there are many people of all backgrounds who have integrated well. It's not about individuals, it's about an average of the whole group."
"Perhaps you can enlighten me as to the usefulness of average to explain the ability of Muslims to integrate into American - or Slovak, for that matter - society. I am all ears."
As there are realtively few Muslims in the US, I don't think it makes sense to talk about statistics here. There are millions of Muslims in Europe (many of them born in Europe). You can google the statistical data on Muslims in Europe yourself.
"Or perhaps that there is a greater income disparity among white Christians and any other ethnic group. Or that Muslims are among the least criminal people in the USA per capita...? Is that what you meant? Probably not. But I'm not surprised. You keep asking if I know what a statistical average is so I'm going to be forced to assume that you do not." Here are some statistics for you - https://en.wikipedia.org/wiki/Poverty_in_the_United_States#By_race.2Fethnicity_and_family_status.2C_based_on_data_from_2007.
"Yes, every race is able to assimilate into the US within one or two generations. Every religion, every ethnicity."
You don't know that because so far you haven't had a large influx of Muslims, unlike Western Europe. The vast majority of immigrants into the US have been Europeans and Hispanics.
"Being star athletes, intellectuals, teachers, doctors, lawyers, business owners, business leaders, soldiers, clergy... that's not integrating? Perhaps you mean paying taxes and sending their children to school and learning the language. Which they do."
Yes, many of them do, but not enough of them. You can google the statistics on employment, poverty and crime yourself, it's pretty obvious. And it doesn't matter whether you take the mean, the median or the mode. Or you could visit Western Europe and see it with your own eyes.
I don't know what the simplest of your questions is. I'm not pretending to be Slovak, I am Slovak. I'd be happy to continue this discussion in Slovak or Czech.
