It's not rude, just a bit weird. Irish people call it Ireland unless making the distinction between the British bit and the not British bit. Then it's referred to as The Republic (as opposed to The North).
Our government should though, but instead they think putting the economy first and their mates in trade is the right thing to do, create a huge problem with loads of deaths and then end up firefighting.
Very similar to a tragedy involving a tower block in London not that long ago.
