Address the issue of people coming from elsewhere integrating into a society/culture that is not their own . . . Like the Hyksos in Egypt or the Europeans in the Americas, etc. - I think you will find a pattern. There are things people bring with them that makes it hard to be fully integrated into their environs - I think that is all Karibkween is saying with historical examples to back her up. Whether or not this applies to Rasi is a another issue entirely, but at least understand the critique.
