As an Irish person (raised Catholic, lapsed) that I do feel for the Jewish people in Ireland.
However, just because you might be Jewish, doesn't always equate that you are Israeli. I have no issue whatsoever with people who practice their Jewish faith.
I do have a massive issue with the way that Israel is going to war with whomever they feel like pissing off next and carrying out a genocide while the world watches on. If, by being a little bit vocal about that and that happens to get under the skin of the Israeli Government and their representatives, then good.
It took a few Irish workers in Dunnes Stores to stop handling goods from South Africa to shine a spotlight on apartheid (source) so I think we can and do have power on an international stage and what we think matters. We can move mountains if we put our minds to it and we can change the world, a bit at a time.
