That's where you are very wrong. That same 33% has been consistent in our opposition to the Liberal Agenda. Up until now, many had thought that FF and FG were socially conservative parties. New it's clear that they have rejected traditional Irish family values.You're so single issue focused you don't get it, only a small fraction of your 33% who voted against abortion see it as an overriding existential issue that there should even be a party for it. Any such party you're envisaging would only be as successful as Renua.
As for SF, Peadar might have gone against party policy, but choosing to let a single issue disagreement be a reason to lose such a star performer is utter stupidity on the parties part.
But hey just like old Labour, SF's new Labour is all about petty grievances when someone dares upstage their betters.
