In the context of current events (i.e. the murder of George Floyd and subsequent BLM protests), I’ve seen claims that black people aren’t the only folks who had to deal with shoddy treatment (the implication being that black people should just suck it up and get on with their day, just like those other downtrodden folks did). Perhaps most notably, Irish folks reportedly had a hard time of it during certain periods of US history; this fact is even used for darkly comic effect in Blazing Saddles, when the townspeople finally surrender: “we’ll take the niggers and the chinks, but NO IRISH!”
My gut feeling is that no racial/ethnic group has been treated as badly or for as long as black people; for example, I’m not aware of an equivalent of Jim Crow laws directed toward the Irish, or lynchings, or separate-but-equal schools, drinking fountains, and so on.
But I don’t know exactly what they did* face. So…how bad did Irish immigrants/descendants have it in the US? What about other minorities? When/why did things get better for them?
