Shouldn't the IRA/RIRA/PIRA/pissed off Irishmen with guns do something about this?
RIRA are ineffectual and obsessed with restarting open conflict with the british, PIRA are disarmed. the IRA also have as a policy not attacked the free state/republic since the civil war.
Or don't they care about Ireland as long as the Irish are the ones destroying it?
See Sinn Féin's policy towards multiculturalism and mass immigration for an answer on that.
Republicanism is dead: failure to adapt.
Tarawatch unfortunately have no emphatic political supporters of any sort. The green party, who promised to stop the m3 if they got into govt, went back on their support for Tara as soon as they got into power. The other two big opposition parties mildly picked up on the matter when it was of use to them (election time) but have since been very quiet.
Ireland is rotten to the core.
