I live in Ireland and am baffled by why people consider themselves akin to the Palestinians. They aren't - the average Gazan would consider Irish people to be pork eating infidels.
I think there are a number of reasons: an Israeli/Jewish perspective or historical background is never presented - particularly by RTE, which issues reports by Hamas' "Health Ministry" verbatim - forgetting their usual obsession with fact checking. People are never told about the thousands of Jewish communities from Morocco to Tajikistan that have perished under Ottoman and other Arab/Muslim expansion, and that Israel is the only remaining territory in which Jews have a chance of defending themselves.
The Israelis are a convenient fit for the need for a baddy among the virtue signallers that fill the major political parties - as long as nobody looks too deep.
Casualty numbers are substantial - as Hamas knew they would be, but there is no genocide. There would have been had Hamas not been stopped on October 7th. Hamas would slaughter until no Jews remain as per their stated objectives. The Israelis have no such goal, but are continually forced to react defensively.
The media in Ireland is full of the heroics of their battalion of UN peacekeepers - there to monitor the peace. As far as I can gather, they have been sitting and watching Hezbollah missiles flying overhead from Lebanon into Israel for a good number of years now.
