The snobbery with which some Irish folks treat the diaspora is really ugly. It's also one of the main reasons that those Irish who came to the UK in the 1950s and 1960s are one or the most isolated impoverished demographics in Britain today. For a lot of people of that generation the attitude of the likes of
@patty123 towards those who emigrated and their kids is the exact reason they never came back or maintained ties with family back home, and one of main reasons a lot of 2nd gen Irish over here found it easier 'became English' than to retain their heritage. Aside from the human cost, the potential and talent that that mindset has squandered is immeasurable.
If I was an Irish person born in Ireland I'd be chuffed if people who took the difficult decision to leave still felt enough of an affinity to make a positive contribution. The one thing I'd say to the Irish-born Irish who sneer at the diaspora is that they should look back and remember that it very easily could have been their family who had to leave, their family who had to deal with being discriminated against in England and being shunned by folks at home.
