What percent of those imports in history were refugees? It's not like we took them in out of sheer goodwill. Abraham Lincoln took lots of Irish and disproportionately had them killed as draftees. FDR only took in the early Jews fleeing Nazi Germany, many of whom educated and/or wealthy, we didn't take in the poor ones.
This is a complicated question because "refugee" as a word wasn't really used in the same way we do today until the UN codified it's definition in 1951(?[going off the top of my head it]). Google NGram depicts this well (and the slight spike in the 1860s is informative).

In any case, waves of migration to the US were usually spurred by economic and political unrest. The Irish are an easy case here, and they were also the first we tried to keep out by requiring a minimum amount of square-footage per head on a boat. Germans were affected by the same potato blight and also faced political prosecution after the failed 1848 revolutions. Eastern European Jews came en masse from their schtetls after the Russian autocrat started encouraging pogroms in the late-19th early 20th-century. I don't know much about the Italians. How many of them specifically could have been designated refugee is a different question, but I think it's safe to assume a fair amount. Most came from countries where they faced political persecution. France's nack for falling to revolution probably plays into why we never received large inflows from France (well, that and the existence of Quebec). FWIW Washington himself designated the US as a land whose "bosom is open to receive the prosecuted and oppressed of all nations."
We excluded the Chinese in the 1880s, but didn't have much of an immigration system otherwise until after WWI. Law, in addition to political calculation, played into refugee policy in the 30s and 40s.
Can you post the German statistics?
I spent way more time on this than I wanted to and still couldn't find what I was looking for because general crime statistics from the BKA seem to divide it up by the different states, and I'm not interested in spending the time with that math. It's also quite impossible to find comparative statistics, and, adding to that, crime statistics have jumped and plummeted over the last few years, flux with rapidly changing circumstances. At the peak of the crisis, it was a mess because they were, of course, not prepared, and many lived in camps with terrible conditions for an extended period of time, which plays into the crime spikes immediately following the influx.
I'm going to be brief because I've gotta run in a few.
I'll start out with what the crowd wants: sexual offences. I couldn't find an article on 2018, which is frustrating because crime has plummeted since the dust of the crisis settled. A little bit on what's in it: the theme plays on the groping scandal; reported sexual offences are in fact higher with refugee populations; most offences happen in asylum shelters themselves.

Here you can find the most recent official report, post-crime plummet. Crimes are lowest among refugees from nations at war, particularly Afganistan, Iraq, and Syria. Overall, crime has dropped among the populations.

Crime dropped by 10% last year, the most significant drop since 1993, right after all those East German migrants were brought in.

Right-wing extremist crime, however, has spiked and is the highest in 15 years, about 24,000 in total. Left-wing crime has dropped 25%, to 1702 in total.

I'll end with something that pissed me off. Fucking Gatehouse, of course they're publishing pieces in German and stoking the right. They do quite a lot of that nice, provocative crime pornography, by naming names of a few victims, and then adding some other lists. In any case, they do say one thing I think is important: that actual figures are likely higher than reported, which I agree. However, this applies to both refugee/immigrant and native born Germans, and is likelier more true for the latter als the former. #MeToo has certainly shown just how pervasive it is and how often it goes unreported.

When large numbers immigrate together it makes assimilation harder because they don't have to assimilate. Throw on top of that the "progressive" dissonance claiming that assimilation is oppression (but Americans need to "immerse" themselves in foreign cultures) and you have a recipe for unrest.
That's not the case in Germany. Integrationspolitik is a big deal and every step in the migration process directly relates to integration policies.
For what it's worth, it's not the case in the US either. I know you like to take handful of hystericals on campus and pretend their views were mainstream (they would like that of course), but they're not and you're casting straw men.
last I saw was that crime stats stopped reporting race/ethnicity to curb a response to the violence/hysteria/whatever it is
Race and ethnicity I'm unsure of (it's not allowed in FRA, for example, because the constitution doesn't allow it), but the thrust of your point isn't correct. They do collect statistics specifically regarding immigrants/refugees.
