Pitying poor refugees and granting them sanctuary in large numbers is always a mistake. Wikipedia on the Gothic War of 376-382.
In the summer of 376, a massive number of Goths arrived on the Danube River, the border of the Roman Empire, requesting asylum from the Huns. They came in two distinct groups: the Thervings led by Fritigern and Alavivus, and the Greuthungi led by Alatheus and Saphrax. Eunapius states their number as 200,000 including civilians, but Peter Heather estimates that the Thervings may have had only 10,000 warriors and 50,000 people in total, with the Greuthungi about the same size. The Cambridge Ancient History places modern estimates at around 90,000 people total.
The Goths sent ambassadors to the Eastern Roman Emperor Valens requesting permission to settle their people inside the Empire….
Many Goths inside Roman territory joined Fritigern, as did assorted slaves, miners, and prisoners. Roman garrisons in fortified towns held out, but those outside of them were easy prey. The Goths created a vast wagon train to hold all the loot and supplies pillaged from the Roman countryside, and they had much rage against the Roman population for what they had endured. Those who had started as starving refugees had transformed into a powerful army.
34 years later, Rome was sacked by Alaric. The same thing is going to happen to various cities in the USA and Europe if the “poor refugees” are not expelled from the West within the next 15-20 years.
But if your society collapses amidst ethnic violence, at least you can console yourselves with the knowledge that no one called you racist.
