If you want Portland on steroids, you want West Cork, e.g. Skibereen or Clonakilty. There’s a huge counter culture community down there, some I agree with, some I don’t (anti vas sentiment is high down there, but that’s a subject for another thread). Lots of immigrants for lifestyle, rather than econmic reasons, and a distinct live and let live ethos. Nearish Cork airport, but, to be fair, still fairly small.
Trans is a funny issue over here. As Karaddin notes, the feminist movement and most women’s rights groups are proudly trans inclusive, with some exceptions. However, in the majority of the country, it feels like trans hasn’t permeated consciousness. In a way, stealth may be easier rurally, as it’s just not a thought someone like my 60ish y/o Dad would consider in the first, second or third instance. It’s becoming slightly more prominent, but not hugely from what I can see. I didn’t watch it, so possibly shouldn’t comment, but RTE, the state broadcaster, recently put out a series called my trans life. Might be worth digging out.
