All the anti-abortion slogans in the world won't do a lick of good if you are following the conciliar church. It wasn't until after Vatican II that the abortionists gained the most ground.
Like most countries, the 'pro-life movement' in Ireland follows the conciliar church. Christ has been dethroned and rarely if ever will a 'pro-lifer' speak of the Social Kingship of Christ. People are not aware.
I suppose in the early days the pro-life movement in Ireland was influenced by the SSPX but these days the JPII 'new evangelisation' and the Friars of the Renewal, and likes of Lila Rose are now the figures of influence.
The new generation takes a different approach.Instead of saying the rosary, the new 'weapon' is a 'flash mob'. It attracts young people. I keep telling them it's silly but as I'm 30+ years of age, I am an 'old fogey'. Personally, I think dancing around to 'Waka,Waka, this is Africa' in an Irish city is silly.
