Ok. I'd love to have a chat about this but it'll start out a bit scattered.

The crux of the problem is that the institutions and groups pushing for a no have historically been the ones pulling the strings and dominating discourse.

In terms of whopping generalities (to which there are many exceptions) the arguments for no derive from catholic dogma- from the original constitutional definition of the family and the place of the women in the home put in by McQuaid for example. What we have now is (as far as I can tell and I hope I'm not being unfair) a minority of people who's beliefs on stuff like the role of marriage, whether life begins at conception and similar, are either informed by or at least correlates with that religious teaching. Since the 80s it has become more and more impossible for any group to argue purely on that basis so gradually for each campaign like divorce or the 8th these groups have been campaigning on the basis of threadbare intellectual arguments but powered by the weight of feeling that such a monumental shift would naturally bring on.

I'd say it's a very uncomfortable time for many 'no' voters and I have great sympathy for that- something divisive like this is likely to make them feel weirdly less of a part of what Ireland is becoming. The problem is that everyone else was confronted by this internal crisis at one point before now, came through it, and didn't start stealing babies from outside supermarkets to sacrifice.

At the same time, I would counsel a bit of reflection to any 'no' voter who is feeling put upon and shouted down. Just as it might be a bit alienating to be campaigned against, anyone with a view outside of catholic dogma has been liable to be brutally alienated for the last hundred years.

tl;dr- it's a bit rich to say 'no' voters have been shouted down. Everyone else has been shouted down and much, much worse since the foundation of the state.
