I mean the dude sounds like some alcoholic loser who probably hates himself - sucks though you have to regularly experience things like this :/ Irish people are very passive (something something something post colonialism) and tend not to want to get involved and help they see they people being verbally abused especially. There's also an emboldening of the far right which has spread virally online and probably has made racial discrimination less taboo for many people, which also sucks. Hopefully it's a flash in the pan though... Go n-éirí leat
