I'm Irish and am very worried about this as gender ideology is being swallowed unquestioningly by people I know who are usually quite sensible. These are people who campaigned for Repeal the 8th so that women could make their own choices about their bodies, yet refuse to concede that there is a conflict if we allow anyone to say they are a woman and as a result give them access to women's spaces and services.
I think a generation of 20/30/40 somethings are high on the success of the campaigns for gay marriage and abortion rights (which I fully support). Those campaigns engendered a great sense of well-being, community spirit, an opportunity to kick against older attitudes, and a declaration that the era of the same old men telling people what to do was over. Those campaigns were probably the first time many of those people were involved in activism and though the campaigns were for very important rights, tackling serious and emotive topics, the campaigning could also be fun and for many it was easy to "campaign" and be involved through the use of social media. So, a huge number of people have the campaign bug and see this as the next great progressive cause.
Fellow Irish people, don't flame me for this, but I don't think, in general, there is a culture of debate and critical thinking. We are great at talking, but not debating and questioning. I remember being really uncomfortable being with groups of French people who would really 'discuss' current affairs or social or political issues because I thought friends were arguing each other. And the same with Americans who have had good educations where the Socratic approach to questioning seems to be fundamental to their education. Whenever I have a "discussion" with friends in Ireland, we have a lovely time as long as we are all in agreement. But raise a contrary opinion and try and open it up to debate and things get uncomfortable and someone makes a joke and changes the topic. And if you know you have opposing views on something, but you love each other anyway, you just avoid the topic altogether.
Things may be changing now with the much younger generations, but the generation that will allow gender ideology to take root will be those who were educated under a system where someone, usually a man, held forth on a subject (a teacher, a priest, the president of the local GAA club) and we listened and accepted what they said and didn't question it too much because it seemed as if everyone was in agreement and fellahs like that with authority must know what they are talking about. If the loudest voices in the gender ideology wars are the TWAW-everything-is-transphobic-misgendering-is-literal-violence brigade (and they are always the loudest voices), then the majority of people, even if they have some misgivings, will think, 'Ah, sure, they must be right, tis terrible if the children are killing themselves".
However much Ireland thinks it has moved on from the past, you don't shake a characteristic like that overnight. I have friends, a couple, who campaigned really hard for Repeal which was very important to them for personal reasons. They are very progressive and the husband sees himself as an ally to women. He sees no contradiction in Tweeting about 'TERFs' and liking posts that are abusive to anyone (women usually) expressing gender critical opinions. He thinks that TWAW. His sister was the victim of a violent sexual assault by a stranger, yet he sees no issue in allowing transwomen to use single-sex spaces. He thinks we have discussions and debates, but he does that old thing of 'man holding forth'. Because he is right about everything of course, so there is no debate.
People are terrified of not being seen as progressive. And yes, if the UK is seen as TERF Island, then we will do whatever we can to make sure we are TRANS Island. What I find (almost) hilarious about this is that once again, it's men who will benefit and women (in the traditional sense) who will be screwed over. It was ever thus in Ireland.
