I think it really depends on the foreign nationals, nationally, skin colour and ethnicity on how well there treated in Ireland. A White Christian Ukranian may have a very different story to a Pakistani Muslim.
I am going to share with you all that I have a daughter with a different ethnicity to me. She made me cry on Friday. She told me that she is in her angry upset words "I am Fucking Irish, but I will never be accepted as Irish in this country". But I keep hearing but we don't mean your daughter. I sit at work having to listen to people in there 40' to 60's spouting the nonsense I've read on this thread. I have to go into work tomorrow, knowing I have to listen to more of it and knowing how my daughter is feeling. I'm sick of listening to "I'm not racist but" and "we just have concerns".
If you think we've done pretty well considering, then how about you come to my house and tell my beautiful, kind, considerate, intelligent daughter that. When she is hurting at the moment and scared to go out and about. In all fairness she has not come across racism in her school primary and secondary but it's just not good enough that she feels like this.
