That’s crazy! You mean like the greenbook that was written for traveling Black Americans during the Jim Crow era so they could avoid places like sundown towns and businesses that refused services to POC? Sorry if that’s not what you meant, it’s the only greenbook I’m familiar with… unless greenbook is a general term for avoiding places filled with racism?

Either way I had no idea that prejudice towards the Irish was still prevalent up into the 80’s. Thats…really something else.
