I agree, most Irish people know nothing about what's been happening in terms of legislation and public sector policy in this area. My family certainly know nothing about it, despite watching RTÉ news and current affairs every day, listening to RTÉ radio daily, and reading the Irish Times - the self-ID legislation didn't get much coverage at the time and so they knew nothing about it.
When I tell them about it, the women in my family all get the implications and aren't in favour of gender identity - they want single-sex spaces and biological sex to be the determination of male and female. They're horrified at the male prisoners in Limerick gaol and they are so upset when I explain what's happening with regards to medicalising gender non-conformity in children.
The men are different in their reaction, they pride themselves on being liberal and progressive (not like the old Ireland) and they think they're not sexist (I and my female relatives would disagree - they're better than their fathers' generation but still wouldn't do a hand's turn around the house without being explicitly asked to help) and they immediately sympathise with the males in Limerick gaol - they think "it's a pity of them that there's something wrong with them and sure why not put in extra guards and let them be in the women's gaol". When I explain that the male prisoners haven't (and probably won't) have surgery and that they were sentenced for attacking women physically and sexually, the men get miffed with me for pointing out a problem with their 'solution' and they give me a load of guff about "well, we have to put them somewhere and the women will be protected by the extra guards". The concept that women don't want (sex-offender) males with them in the gaol seems to pass by my male relatives as information that's unexpected but not really a valid objection.
These are men who agreed wholeheartedly with the judgement in the Asher's Bakery case, that someone can't be compelled to support or agree with something against their own personal beliefs. Yet, when it comes to Irish women standing up for their sex-based rights and protections, these men become much less liberal. It's exasperating but I don't know why I was surprised, I mean I've been putting up with sexism and disdain, and being seen as less important than male citizens, from the Irish State and Irish men for nearly 50 years now.
